contains chemicals known to the State
of California to cause cancer, birth
defects and other reproductive harm.
Some examples of these chemicals are:
Leadfromlead-basedpaints.
Crystallinesilicafrombricks.
Cementandothermasonryproducts.
Arsenicandchromiumfromchemically
treatedlumber.
Your risk from these exposures varies,
depending on how often you do this type

HS81A CUT-OFF SAW — BLADES
PREPARATION / PRE-INSPECTION
1. Read and fully understand this manual,
the safety instructions in particular, and
the engine manufacturer's manual
supplied with the saw.
2. Select the correct blade for each application. If abrasive
blades are used, MAKE CERTAIN they are designed for
use on a concrete floor saw. They must be reinforced and
have a hole for the driving pin. When wet cutting with an
abrasive blade, MAKE CERTAIN the blade is intended for
wet cutting. Water will destroy a dry cut abrasive blade.
Some diamond blades require water cooling and failure to
do so will destroy them almost immediately. Other diamond
blades can be used with or without water.
3. Handle all blades with care and NEVER use a damaged
blade. NEVER use an abrasive blade that has been
dropped.

BLADES
Saw blades, or cutting disks, are available in either an abrasive
design or as diamond blades. Either blade will work on the
HS81A CUT-OFF SAW , however, diamond blades are recommended.
Ask your dealer about your specific cutting application.
SAW BLADE INSPECTION

WARNING

Failure to thoroughly inspect the diamond
blade (Figure 12) for operational safety
could result in damage to the blades or
the saw and may cause injury to the user
or others in the operating area.

1. Stress Relief Holes (Gullets) - Check the steel core for
cracks that may have propagated from the slots and/or
gullets. Cracks indicate extreme fatigue failure and if sawing
continues, catastrophic failure will occur.

Figure 12. Diamond Blade
2. Edge of the Steel Core - Check the diameter edge for
discoloration (blue oxidation) indicating an overheating
condition caused by insufficient cooling water/air.
Overheating of blades may lead to loss of core tension and/
or increase the possibility for blade failure. Make sure the
steel core's width is uniform about the rim of the blade, and
not succumbing to an "under-cutting" condition brought
about by highly abrasive material or improper under-cutting
core protection
3. Directional Arrow - Ensure that the blade is oriented
properly on the blade shaft for sawing. Reference the
directional arrow on the blade and place it so the direction
of rotation "downcuts" with the turn of the shaft.
4. Diamond Segment or Rim - Ensure there are no cracks,
dings, or missing portions of the diamond segment/rim. DO
NOT use a blade that is missing a segment or a portion
of the rim. Damaged and /or missing segments/rims may
cause damage to your saw or injury to the user or others in
the operating area.
5. Specifications - Ensure that the blade specifications, size,
and diameter properly match up to sawing operations.
Utilizing a blade not matched properly to the task may result
in poor performance and/or blade damage.
6. Arbor Hole - It is essential that the arbor hole diameter
properly matches the blade, and that it is free from distortion.
Correct blade flanges (collars) must be used. The inside
face of the flanges must be clean and free of debris. An outof-round arbor condition will cause damage to the blade
and the saw.
7. MAX RPM - This RPM reference is the maximum safe
operating speed for the blade selected. NEVER exceed the
max RPM on the diamond blade. Exceeding the maximum
RPM is dangerous and may cause poor performance and
may damage the blade.

DO NOT use automotive motor oil when
adding oil to fuel. For optimum performance
and proper lubrication, the manufacture
recommends that the fuel to oil ratio mixture
be 25:1

A single bottle ( 2.6 fl. oz) of smokeless 2-stroke motor oil cannot
be purchased separately. However you can purchase from
Multiquip a case (P/N 00325) of 48 individual bottles or a 6 pack
(P/N 003256PAK).
Starting
1. Place the engine ON/OFF switch in the ON position
2. Using your thumb, press down on the throttle lock lever,
while squeezing the throttle trigger. This will lock the throttle
in the half-throttle position.
3. Pull the choke lever all the way out to the CLOSED position.
4. Pull the decompression button outward.
5. Place the saw on level ground. Make sure the saw blade is
free to rotate and will not come into contact with any foreign
objects.
6. Hold the front handle firmly with the left hand and put your
right foot onto the base of the rear handle.

NOTE

The CLOSED position of the choke lever
enriches the fuel mixture for starting a COLD
engine. The OPEN position provides the
correct fuel mixture for normal operation after
starting, and for restarting a warm engine.

HS81A CUT-OFF SAW — OPERATION & PARTS MANUAL — REV. #2 (07/26/10) — PAGE 19

HS81A CUT-OFF SAW — INITIAL START-UP/OPERATION
7. Grasp the starter grip and slowly pull it out.The resistance
becomes the hardest at a certain position, corresponding to
the compression point. Pull the starter grip briskly and smoothly
for starting.
8. If the engine has started, slowly return the choke lever to the
"OPEN" position. If the engine has not started repeat steps
1 through 9.
9. Squeeze the throttle lever trigger to release it from the halfthrottle position.
10. Before the saw is placed into operation, run the engine for
several minutes. Check for fuel leaks, and noises that would
associate with a loose guards and/or covers.

NOTE

Mark the cutting line clearly and always
saw in a STRAIGHT LINE ONLY.

4. When the end of the cut has been reached, raise the blade
out of the cut .
5. If cutting is complete, turn the engine off and wait for the blade
to stop rotating.
Shut-down
1. Let the engine idle for 3-5 minutes.

OPERATION

2. Place the engine ON/OFF switch to the OFF position

WARNING
ALWAYS cut with the saw at FULL THROTTLE. Attempting to
cut with the saw at less than full throttle could cause the blade to
bind or stop abruptly in the slab resulting in serious injury to the
operator or others in the area.

3. Wait for the blade to stop spinning before handling the saw.
4. DO NOT touch the cutting blade it is very hot!, allow it to
cool, severe burn condition exists.

WARNING
ALWAYS keep clear of rotating or moving parts while operating
this equipment.
2. To begin sawing, lower the rotating blade allowing it to cut to
the preset depth.
3. When blade has reached full cutting depth, slowly walk
behind the saw at a rate that will allow the engine to operate
without losing optimum RPM.

CAUTION
DO NOT try to cut faster than the blade will allow.
Cutting too fast will cause the blade to rise up
out of the cut. Improper cutting rate can decrease
the life of the engine and blades.

provisions:
1.

A Returned Material Authorization
must be approved by Multiquip prior to
shipment.

Obsolete parts. (If an item is in the

returned to the sender at his expense.

The parts numbers and descriptions

The list must be typed or computer

10. In cases where an item is accepted, for
which the original purchase document

based on the list price that was effective
twelve months prior to the RMA date.

A $35.00 surcharge will be added to the
invoice for special handling including bus
shipments, insured parcel post or in cases
where Multiquip must personally deliver the
parts to the carrier.

LIMITATIONS OF SELLER’S LIABILITY
Multiquip shall not be liable hereunder for
damages in excess of the purchase price of
the item with respect to which damages are
claimed, and in no event shall Multiquip be
liable for loss of profit or good will or for any
other special, consequential or incidental
damages.

LIMITATION OF WARRANTIES
