models) for mounting manually operated trolley to hoist. Trolley must be ordered separately; see page 21.
INSTALLATION
WARNING
THE HOlSTlNG EQUIPMENT SHOWN AND DESCRIBED
IN THIS MANUAL SHALL NOT BE USED TO LIFT OR
TRANSPORT HUMAN CARGO.
The hoist shall be installed only in locations that will permit
the operator to stand free of the load at all times.
Your ARO hoist is completely lubricated and load tested
before being shipped from the factory. To place in service:
HOOK SUSPENDED MODELS:
Select an overhead support capable of safely supporting
combined weight of hoist and its capacity load. Hang hoist,
being certain the upper hook is firmly seated in the center of
the hook saddle and that the safety latch is properly closed.
The use of a secondary safety cable is recommended, see
page 21.
TROLLEY SUSPENDED MODELS:
The trolley side plates must be spaced so the trolley wheels
will properly engage the beam on which the trolley will be
operated. Adjustment for various beam sizes is
accomplished by arrangement of the spacer washers on the
shaft which connects the trolley side plates. The hoist can be
suspended from the trolley by using trolley adapter
(part number 47717 for 1/4 and 1/2 ton hoist models, part
number 47716 for 1 ton hoist models) or by attaching the
upper hook directly to shaft (figure 1). Use of the trolley
adapter is recommended.
The distance between the outside edges of the trolley wheels
should be approximately 1/2” greater than the width of the
beam flange. The number of spacer washers used to space
side plates out must be the same on each side of the shaft
(or trolley adapter) and the remaining spacers must be
equally distributed on the shaft outside the trolley side plates
at each side between the side plates and lock nuts,
(see figure 1). When installing the trolley on the beam, be
certain side plates are vertical.
Assemble trolley adapter to hoist housing. Determine the
number of spacer washers needed to properly space side
plates for beam to be used, and assemble shaft to trolley
adapter. Assemble spacer washers, side plate, spacer
washers and nut to one side of shaft. Position trolley and
hoist on beam and assemble spacer washers, side plate,
spacer washers and nut to other side of shaft. Tighten nuts
securely. The lock nuts must properly engage shaft extending
all the way thru the nut; see page 21 for trolley and adapter.
The trolley wheels should be positioned as close as possible
to the edge of the beam flange. Operate the trolley over the
entire length of the beam track and observe operation. If it
appears the trolley side plates can be moved closer together
and freedom of movement maintained, remove an equal
number of spacer washers from between the side plates and

trolley adapter at each side and assemble these spacers to
the outside of the side plates between the side plate and lock
nuts.
The beam on which the trolley is to be used must safely
support the combined weight of the hoist, trolley and capacity
load. Minimum turning radius of the trolley is 24” for 1/4 and
1/2 ton models; 36” for 1 ton models.
Connect hoist to nearest air source using a minimum 1/2” i.d.
air hose assembly. Sufficient air hose must be provided to
reach the farthest point of travel of the trolley.
ARO model 7703 hose trolley assemblies are recommended
to keep air hose elevated and in line with the hoist,
see page 24.

AIR AND LUBE REQUIREMENTS
AIR PRESSURE of 90 p.s.i.g. (6 bar) at the air inlet of the
hoist is required for maximum motor efficiency. If necessary,
an air regulator should be installed to maintain this pressure
when hoist is in operation.
FILTERED AND OILED AIR will allow the hoist to operate
more efficiently and yield a longer life to operating parts and
mechanisms. A line filter capable of filtering particles larger
than 50 microns should be used with a line oiler.
FILTER-REGULATOR-LUBRICATOR (F-R-L) assembly
model 128241-300 is recommended for use with each hoist.
The capacity of this F-R-L is adequate to provide clean
(40 micron) oiled and regulated air for the hoist. The F-R-L
must be installed on the stationary air line, in that order, with
the lubricator nearest to the hoist.
LOAD CHAIN LUBRICATION - Chain should be lubricated
periodically with heavy “EP” Gear Oil. Occasional cleaning of
the chain under normal operation conditions will tend to
reduce wear and prolong chain and pocketwheel
(or sprocket) life. To properly clean, remove chain from hoist
(see page 7) and wash in an oil solvent. Lubricate chain.
Under highly contaminated operating conditions, the load
chain should be cleaned and relubricated with greater
frequency to remove grit, sand and other contaminants.
OIL RESERVOIR in head should be filled with spindle oil
(29665) after each 40 hours of operation.
INJECT GREASE (33153), 2 to 3 strokes, thru grease fitting
in hoist housing to provide lubrication for gearing, and thru
fittings of trolley wheels a minimum of every 160 hours of
operation.
LOWER BLOCK ASSEMBLY should be lubricated at any
time the lower block is disassembled either for inspection or
for maintenance or for chain replacement. See pages 16 and
17 for lubrication instructions.
RECOMMENDED HOSE SIZE - 1/2” (13 mm) nominal inside
diameter.
RECOMMENDED LUBRICANTS: Spindle Oil 29665,1 qt.
(.9 liter) container for oiler and air inlet; Grease 33153,5 lb.
(2.3 kg) can for gears, lower block and bearings; “O” Ring
Lubricant 36460 4 oz. (113 g) tube for lubrication and
installation of “O” rings.
OPERATION
OPERATE HOIST CAUTIOUSLY to become familiar with the
performance of the hoist. Hoist shall be operated from a
position that will not be hazardous to the operator. Abrupt
operation, resulting from “jerking” of controls, should be
avoided.
The rate of lift or descent of any ARO chain hoist can be
governed manually by the operator, Both the pull chain and
pendant controls provide unlimited variation between full
speed and the slowest “INCHING” movement. This is
accomplished by movement of pull chain handles or pendant
control levers. Pulling down on pull chain control as far as
possible or depressing pendant control levers fully will result
in maximum hoist speed.
On pendant control models, the control handle is supported
by a strain cable to prevent stress on hoses.
BEFORE STARTING TO LIFT, ensure chain is properly
seated in the sprockets (or pocketwheel). Do not lift or move
load more than a few desinches until load is well balanced in
sling or lifting device. Care shall be taken in hoisting to
ensure that chain is not kinked or twisted and load does not
contact any obstruction Be certain hoist is centered over load
to prevent danger of load swinging when lifted. Side or end
pulling should always be avoided. Take up slack chain
carefully to avoid overstress caused by jerking load when
lifting. Be certain that safety latch on load hook is properly
closed. On 1 ton link chain models to avoid jamming of chain
in lower block, allow only sufficient slack in chain to permit
attaching hook to load.
DO NOT wrap the hoist chain around the load. The load shall
be attached to the hook by means of slings or other approved
devices and shall be properly seated in the saddle of the
hook.
The maximum lift rate of a hoist is constant, provided that air
pressure and load are also constant. The maximum descent
rate of a hoist, with the exception of spark-resistant models
(see spark-resistant hoist section), can be varied within fixed
limits by means of regulating valves located on the underside
of the head housing.
Hoists are shipped from the factory with regulator valves
pre-set for rate of descent and fastest rate of lift. If a faster
rate of descent is desired, turn regulator valve clockwise by
small increments while testing with desired or rated load
attached. If a slower rate of lift is desired, turn regulator valve
counterclockwise by small increments while testing with
desired or rated load.
The operator shall test the brakes each time a load
approaching the rated load is handled by raising the load just
enough to clear the floor, or supports, and checking for
proper brake action and lift continued only if brake is
functioning properly.

WARNING
MAXIMUM LOWERING SPEED WITH RATED CAPACITY
LOAD IS VERY HIGH. ADJUST WITH CARE.
Safe and efficient operation of your ARO hoist can be
attained by observing proper operating, inspection and
maintenance procedures. Allow only competent and qualified
people to operate hoist and subject each hoist to a regular
inspection and maintenance procedure. The qualified hoist
operator must be carefully instructed in the safe operation of
the hoist, including a study of the manufacturer’s literature,
and must thoroughly understand proper methods of hitching
loads. The operator should have a good attitude regarding
safety.
To aid in better understanding of proper and safe use of
hoists: the publication “Overhead Hoists”, ANSI B30.
16-1981, can be purchased from the American Standards
Institute, Inc., 1430 Broadway, N.Y., N.Y. 10018.
INSPECTION AND MAINTENANCE
INSPECTION
ARO recognizes the need for periodic inspection of hoist
components as an important step in preventive maintenance.
The type of application for a hoist varies so greatly, it is
impractical to recommend an exact time-table for inspection
of the hoist, Where hoist is subjected to continuous operation
with capacity loads, it is recommended the unit be inspected
daily to weekly. If the application is less demanding, the unit
should be inspected weekly to monthly. In general, the
frequency of inspection should be determined by the severity
of the application.
The user of a hoist should be guided by any existing federal,
state or local regulations governing the use, testing or
inspection of the hoist.
The following points and areas are recommended for
inspection:

LOAD CHAIN AND ANCHORS
a. Visually check for nicked, gouged, twisted, bent,
corroded, rusted, worn or broken links. Check ends of
chain where chain is anchored to hoist frame and where
chain is fastened to lower hook. Check anchores and
pins.
b. Check chain elongation with a vernier caliper as shown in
figure 4. IT IS NOT INFERRED that a chain is safe prior
to the occurence of elongation of the chain. It is inferred
ONLY, that when said elongation is evident, the chain
must be replaced. Other factors, such as those
mentioned as a visual check, may render chain unsafe
long before replacement due to elongation is necessary.
NOTE: New chain should never be used on a worn
pocketwheel. Replace chain and pocketwheel as a pair,
Chain should also be replaced when replacing brake
shoes.
GEARS, BEARINGS AND SPROCKET
a. Check condition of teeth on gears and motor shaft pinion.
b. Check condition of sprocket teeth or pockets of
pocketwheel.
c. Check condition of bearings.
d. Replace any worn or damaged parts.
BRAKE
a. Check brake linings and components,
b. Check brake operation.
NOTE: When replacement of brake shoes is indicated,
they must be replaced as a pair. Also replace chain at
this time.
THROTTLE VALVE HEAD AND GEARS
a. Check condition of valve body, valves and “O” rings on
valves.
b. Check condition of gear teeth and bearings.
c. Replace any worn or damaged parts.
HOOKS AND SUSPENSION
a. Check upper and lower hooks and component parts for
bent, worn, cracked, broken or otherwise damaged parts.
b. On trolley suspended models, check conditions of trolley
parts, trolley adapter and component parts. Replace any
damaged parts.
AIR MOTOR
a. Check end faces of rotor for roughness and blade slots
for wear or burrs, A new blade should slide in and out of
slots without binding.
b. Check blades for wear, warpage or other damage.
c. Check cylinder bore diameter for rough circular grooves
from scoring. A badly scored cylinder cannot be restored
by honing since it will only enlarge bore diameter,
widening seal point between rotor and cylinder, hindering
free exhaust of air and result in loss of speed and power.
d. Check end plates for wear or scoring. Check bearings.
e. Replace any excessively worn or damaged parts.
GENERAL MAINTENANCE
AIR HOISTS are made of precision parts and should be
handled with reasonable care when servicing. Excessive
pressure exerted by a holding device may cause distortion of
a part. Apply pressure evenly when disassembling (or
assembling) parts which have a press fit. When removing or
installing bearings, apply pressure to the bearing race that
will be press fit to the mating part; if this is not practiced,
Brinelling of the bearing races may occur making
replacement necessary. It is important that the correct tools
and fixtures are used when servicing this air hoist.
DISASSEMBLY should be done on a clean work bench with
a clean cloth spread to prevent the loss of small parts. After
disassembly is completed, all parts should be thoroughly
washed in a clean solvent, blown dry with air and inspected
for wear levels, abuse and contamination. Double sealed or
shielded bearings should never be placed in solvent unless a
good method of relubricating the bearing is available. Open
bearings may be washed but should not be allowed to spin
while being blown dry. When REPLACEMENT PARTS are
necessary, consult drawing containing part.
BEFORE REASSEMBLING, lubricate parts where required.
Use 33153 grease, or equivalent, in bearings. Use 36460
lubricant for “O” ring assembly. When assembling “O” rings or
parts adjacent “O” rings, care must be exercised to prevent
damage to the rubber sealing surfaces. A small amount of
grease will usually hold steel balls and other small parts in
place while assembling.
WHEN ORDERING PARTS, be sure to list PART NUMBER,
PART NAME and MODEL NUMBER OF HOIST. USE ONLY
GENUINE ARO REPLACEMENT PARTS.

REMOVAL AND INSTALLATION OF LOAD CHAIN
REMOVAL
LINK CHAIN HOISTS - A new chain should never be used on
a worn pocketwheel. Replace chain and pocket-wheel as a
pair. To remove chain; disconnect end of load chain from
anchor lug on housing by removing screw (Y157-51) and
washer (Y13-4-C). NOTE: Models employing a chain basket,
remove chain stop from end of chain. Chain can be pulled
thru housing by hand while holding brake open, by pulling (or
pushing) on control arm (either end). On 1 ton models,
disconnect opposite end of load chain from anchor bracket
(41624) by removing nut (Y109-524) and bolt (41625).
Remove chain stop and lower hook assembly.
ROLLER CHAIN MODELS - Disconnect end of load chain
from anchor block (44686) by removing connecting link
(33363). NOTE: Models employing a chain basket, remove
chain stop (ring) from end of chain. Chain can be pulled thru
housing by hand while holding brake open, by pulling (or
pushing) on control arm (either end). On 1 ton models,
disconnect opposite end of load chain from anchor bracket
(37579) by removing bolt (37580) and anchor pin (34316).
Remove chain stop and lower hook assembly.
INSTALLATION
LINK CHAIN MODELS - Position hoist in a vise or other
suitable holding device (figure 5) and remove housing cap,
brake spring and brake shoes, Turn brake wheel by hand to
rotate pocketwheel while carefully feeding chain thru chain
guide and around pocketwheel. Pull sufficient chain thru
housing to allow end link of chain to be attached to anchor
lug on housing.
IMPORTANT NOTICE: The link chain must be positioned
around the pocketwheel so the weld on the standing
links of chain face outward from pocketwheel (figure 5).
ALSO, the end link of chain must be fed over
pocketwheel so it will be positioned properly to permit
attaching chain to anchor lug on housing without
twisting of chain (figure 16).
WARNING
DO NOT attempt to feed chain over pocketwheel or
sprocket by air power as chain will be pulled thru at a
very fast rate.
ROLLER CHAIN MODELS - Remove housing cap, brake
spring and brake shoes. Turn brake wheel by hand to rotate
sproket while carefully feeding chain thru guide and around
sproket. Pull sufficient chain thru housing to allow end link of
chain to be attached to anchor block and anchor lug on
housing.
To assemble chain to lower block on 1-TON models, see
page 16 and 17.
BRAKE ADJUSTMENT
To adjust brake, insert screwdriver thru hole in housing cap.
Turn screw (37701) counterclockwise to tighten brake,
clockwise to loosen brake.
Brake adjustment should be made with air turned on and with
rated load attached to lower hook. Operate hoist to raise load
applying slight pressure to pendent control. If load starts to
lower before it is raised by motor, tighten brake until no
slippage is evident. Cure should be taken not to tighten brake
more than necessary to hold load. If brake is too tight, it will
cause erratic hoist control.

SPARK-RESISTANT HOIST SECTION
NOTE: For models with trolley adapter in place of upper hook, add the letter “T” to model number. Example - 7712-ET or-
ELT would be supplied with trolley adapter in place of upper hook.
The hoists listed in the chart above are furnished with load
chain made of stainless steel. The top and bottom hooks of
these hoists are bronze, with snaps.
Other components of the 400 lb. capacity spark-resistant
hoists are comparable to the standard 1/2 ton models, and
the 1000 lb. capacity spark-resistant hoist components are
comparable to the standard 1 ton models, but the rates of lift
and descent are modified. All rates of lift and descent
outlined here are maximum of 90 p.s.i. The 400 lb. capacity,
stainless roller chain hoists have a rate of lift and descent of
approximately 40 feet per minute. The 550 lb. capacity,
stainless steel link chain hoists have a rate of lift of 50 feet
per minute and 70 feet per minute on descent. The 1000 lb.
capacity hoists have a rate of lift and descent at
approximately 10 feet per minute. The 1500 lb. capacity
hoists have a rate of lift and descent at approximately I6 feet
per minute.
SPECIAL NOTE: Spark-resistant models are shipped from
the factory with valves (41595) pre-set for maximum rates of
lift and descent and are secured by set screws (41627-1). DO
NOT ADJUST OR REMOVE VALVES (41595) on these
models. If head assembly is replaced for service, valves
(41595) must be adjusted for the following rates of lift and
descent.
400 LB. and 550 LB. CAPACITY HOISTS - Rate of lift with
maximum throttle opening with a 500 lb. load shall be:
Roller chain models - 40 ft/min. maximum.
Link chain models - 50 ft/min. maximum.
Rate of descent with maximum throttle opening and a 500 lb.
load shall not exceed:
Roller chain models - 40 ft/min.
Link chain models - 70 ft/min.
1000 LB. CAPACITY HOIST - Rate of lift and descent with
maximum throttle opening with 1200 lb. load shall not exceed
10 ft/min.
1500 LB. CAPACITY HOIST - Rate of lift and descent with
maximum throttle opening with a 1500 lb. load shall not
exceed 16 ft./min.
Air inlet adapter (46212) must be used with the 1000 lb.
capacity hoists.

ACCESSORIES SECTION
PIPED EXHAUST
Exhaust from the air motor normally escapes into the room
atmosphere, however, exhaust can be piped out of the room.
The hoist can be furnished, at extra cost, with a modified
head for piped exhaust. An exhaust hose, 1/2” (12 mm)
diameter recommended, can then be attached to this outlet
and air can be ventec at any remote point. Piped exhaust is
highly desirable in applications involving food processing,
chemicals or other processes where atmospheric purity must
be maintained. It is also preferred for its low noise level
characteristics.
When ordering, specify model number and add “with piped
exhaust”.
