ReadOperatingInstructions

Please become familiar with all the instructions and

warnings before operating any pneumatic tool.

Always Wear Approved Eye Protection

impact resistant eye protection should meet or exceed

the standards set forth in ANSI Z87.1, Occupational and

Educational Eye and Face Protection. Look for marking

Z87.1 on your eye protection to ensure that it is an

approved style.

Hearing Protection is Recommended

Hearing protection should be used when the noise Ievel

exposure equals or exceeds an 8 hour time-weighted

average sound level of 85dBA. Process noise, reflective

surfaces, other tools being operated nearby, all add to the

noise level in a given work area. If you are unable to

determine your noise level exposure, we recommend the

use of hearing protection.

Avoid Prolonged Exposure to Vibration

Pneumatic tooIs can vibrate during use. Prolonged

exposure to vibration or very repetitive hand and arm

movements can cause injury. Discontinue the use of any

tool if you experience tingling, numbness, discomfort or

pain in your hands or arms. You should consult your

physician before resuming use of tool.

90 PSI Maximum

This tool is designed to operate at an air pressure of 90

pounds per square inch gauge pressure (90 PSi)

maximum, at the tool. Use of higher air pressure can, and

may cause injury. Also, the use of higher air pressure

places the internal components under loads and

stresses they were not designed for, causing premature

tool failure.

NOTE: THE AIR SUPPLY SHOULD BE CLEAN, DRYAND

PREFERABLY LUBRICATED. FOR BEST RESULTS

DRAIN THE MOISTURE FROM YOUR COMPRESSOR

DALLY.

The Craftsman Model 875.199590 Continuous Flow

Grease Gun is designed for both automotive as well

as heavy industrial usage.

Features

The Craftsman professional Continuous Flow Grease

Gun Model 875.199590 is designed to operate at 60

to 150 PSI. Lower pressure will reduce the

performance of the tool, while pressure higher than

the rated 150 PSl will damage the internal

components to the tool.

• Exclusive air piston design assures self priming.

• Fully automatic; cycles continuous grease flow

when the trigger is depressed.

• Heavy duty spring for prime retention.

• High pressure performance with 60 to 150 PSI

generated at the compressor allows the tool to

deliver 2400 to 6000 PSI (40:1 ratio) of pressure

into the desired fitting.

Some dust created by power sanding, sawing, grinding,

drilling and other construction activities contains chemi-

cals known to cause cancer, birth defects or other

reproductive harm. Some examples of these chemicals

are:

Lead from lead based paint

crystalline silica from bricks and cement

and other masonry products, and

arsenic and chromium from chemically-

treated lumber.

Your risk from those exposures varies, depending on how

often you do this type of work. To reduce your exposure to

these chemicals: work in a well ventilated area, and work

with approved safety equipment, such as dust masks that

are specifically designed to filter out microscopic par-

ticles.

Pre-Operation

Before the tool is connected to the air supply, clear the air

hose of accumulated dust and moisture by running air

freely through the air hose for 5-10 seconds. Before

removing a tool for service or changing sockets, make

sure the air Iine is shut-off at the compressor. This wilI

prevent the tool from operating if the throttle is accidently

engaged.

Installation (See figure 1)

This tool is designed to operate at 90 psi. Lower pres-

sure (below 90 psi) will reduce performance of the tool

while higher air pressure (over 90 psi) raises the perfor-

mance of the tool beyond its rated capacity and could

cause serious damage to tool and user.

Always use clean dry air. Excessive moisture and dirt will

greatly reduce the life of any air motor. We recommend

the installation of an in-line filter-regulator-lubricator as

close to the tool as possible.

A 3/8" air hose is required up to a length of 8 ft. If more

length is required a 1/2" air hose should be used at the

compressor. Attach a 3/8" whip hose for the remaining

4 - 8 ft. for flexibility. Be sure all hoses and fittings are the

correct size and tightly secured before using air tool.

Instructions for the 3 ways to load your grease gun:

1. Cartridge Loading:

A) Remove the canister from the head.

B) Draw the plunger head back completely.

C) Insert the open end of the cartridge into the cannister

of the grease gun. Remove the seal or pull-tab from the

other end of the tube and tightly re-attach the cannister to

the gun head.

D) Press the plunger release valve at the bottom of the

cannister and release the plunger rod and pull down the

plunger handle.

2. Loading with a filler pump:

A) Draw back the plunger handle completely.

B) Insert plug into the filler pump socket. Make sure the

socket is securely fastened to the plug.

C) Operate the grease gun from the filler pump.

D) Disconnect the grease gun from the filler pump.

E) Press the plunger release valve and pull down plunger

handle.

3. Bulk Filling:

A) Remove canister from grease gun head.

B) Draw back the plunger handle completely and bulk fill

grease into empty canister.

C) Re-attach the canister to the gun head and press the

plunger release valve. Pull down the plunger handle and

begin using.

Lubrication

An in-line filter-regulator-lubricator (fig 1) is recommended

as it increases tool life and keeps the tool in sustained

operation. The in-line lubricator should be regularly

checked and filled with air tool oil. Proper adjustment of

the in-line lubricator is performed by placing a sheet of

paper next to the tools exhaust ports and holding the

throttle open approximately 30 seconds. The lubricator is

properly set when a light stain of oil collects on the paper.

Excessive amounts of oil should be avoided.

In the event that it becomes necessary to store the tool for

an extended period of time (overnight, weekend, etc.), it

should receive a generous amount of lubrication through

the air inlet (fig 3). The tool should be run for

approximately 30 seconds to ensure oil has been evenly

distributed throughout the tool. The tool should be stored

in a clean and dry environment.

Recommended lubricants: Use air tool oil or any other

high grade turbine oil containing moisture absorbent, rust

inhibitors, metal wetting agents and an EP (extreme

pressure) additive. (See Fig. 3 for location/air inlet).

Troubleshooting

Tool runs slowly or will not operate 1. Grit or gum in tool 1. Flush the tool with air tool oil or gum

solvent.

2. No oil in tooI

3. Low air pressure

4. Air hose leaks

5. Pressure drops

6. Worn rotor blade in motor

7. Worn ball bearing in motor

2. Lubricate the tool according to the lubrication

instructions in this manuai

3. a. Adjust the regulator on the tool to the maxi-

mum setting

b. Adjust the compressor regulator to tool

maximum of 90 psi.

4. Tighten and seal hose fittings if leaks are found

use teflon tape.

5. a. Be sure the hose is the proper size. Long

hoses or tools using large volumes of air may

require a hose with an I.D. of 1/2" or larger

depending on the total length of the hose

b. Do not use a multiple number of hoses

connected together with quick connect fittings.

This causes additional pressure drops and

reduces the tool power. Directly connect the

hoses together

6. Replace rotor blade

7. Remove and inspect bearing for rust, dirt and

grit. Replace or clean and grease bearing with

bearing grease

Moisture blowing out of tool exahust 1. Water in tank 1. Drain tank. (See air compressor manual). Oil tool

and run until no water is evident. Oil tool again and

run 1-2 seconds

Impacts slowly or will not impact 1. Lack of lubrication 1. Lubricate the air motor and the impact mechanism.

(See Lubrication section of this manual)

2. Adjust the regulator on the tool to the maximum

setting

2. Tool regulator set in wrong

position

3. In-line regulator or

compressor regulator

set too low

3. Adjust regulators in the air system

Impacts rapidly but 1. Worn impact mechanism 1. Replace worn impact mechanism components

will not remove bolts

Does not impact 1. Broken impact mechanism 1. Replace broken impact mechanism components
