4. PREPARATION FOR USE
AIR SUPPLY
Recommended hook-up is shown in fig. 2.
4.1. Ensure that the trigger is in the O position when connecting to the air supply.
WARNING! Ensure that the air supply is clean and is between 40-120psi. (3-8 BAR) Too high an air pressure and/or unclean air will
shorten the life of the gun due to excessive wear, and may be dangerous, causing damage and/or personal injury. The recommended
working pressure is 90 PSI (6 BAR). This grease gun has a 40:1 pressure ratio; i.e. the grease discharge pressure will be 40 times the
inlet air pressure.
4.2. Drain the compressor air tank daily. Water in the air line will damage the gun.
4.3. Clean compressor air inlet filter weekly.
4.4. Line pressure should be increased to compensate for unusually long air hoses (over 8 metres). The minimum hose size should be 1/4”
I.D. And fittings must have the same internal bore.
9 Keep hose away from heat, oil and sharp edges. Check hose for wear and make certain that all connections are secure.
LUBRICATION
4.5. Like all air equipment, this grease gun needs regular lubrication. To lubricate, add a few drops of oil through the air inlet on the grease
gun. It is recommended to use SAE 30 or higher viscosity oil.
OPERATING THE GREASE GUN TRIGGER
4.6. This is a one shot grease gun, whereby there is grease discharge with every press of the trigger.
8 DO NOT keep the trigger pressed during operation. The trigger must be repeatedly pressed and released while greasing. Also, DO NOT
repeat the action too fast, as the piston needs to complete a full cycle before starting a new one.
SETTING UP THE GREASE GUN HEAD
Attach the male quick connect coupler air fitting supplied with the gun onto the air inlet on the die cast handle. The male quick connect
coupler air fitting has ¼” NPT threads and should be threaded into the female hole on the die cast handle using thread sealant. Make sure
the connection is tight so that there is no leakage of air. Use PTFE Tape while connecting the air fitting to the air inlet.
CAUTION: Grease or empty cartridge in barrel is under pressure from the internal spring, use caution when removing either end of the
barrel.

GREASING A GREASE FITTING / GREASE POINT
The grease coupler provided at the end of the grease gun extension
has a jaw type construction. The coupler jaws will snap on to a grease
tting and maintain a tight t. When connecting the coupler to the
grease tting, press the coupler straight onto the grease tting to form
a snug t. Start operating the grease gun with the coupler as square to
the grease tting as possible. Once greasing is completed, slightly tilt
the coupler, twist and pull back. The tilt and twist action will allow easy
removal of the coupler from the grease tting. See g.5.
6. MAINTENANCE
WARNING! Disconnect gun from air supply before changing accessories, servicing or performing maintenance. Replace or repair
damaged parts. Use genuine parts only. Unapproved parts may be dangerous and will invalidate the warranty.
6.1. Lubricate the air tool daily with a good grade of air tool oil such as Sealey ATO/500 or ATO/1000. If the compressed air system has
no oiler, a few drops of oil can be poured into the air inlet of the gun each day.
6.2. When not in use, disconnect from air supply, clean and store in a safe, dry, childproof location.
Note: Faults in the compressed air system may cause loss of power or erratic action. Reduced compressor output, excessive drain on
the air line, moisture or restrictions in air pipes or the use of hose connectors of incorrect size may reduce the air supply.
Grit or gum deposits in the tool will reduce power and may be removed by flushing out the gun with gum solvent oil or an equal mixture
of SAE 10 oil and kerosene.
7. TROUBLESHOOTING
WARNING! If the gun fails to work properly, it may be due to air pockets in the grease. To remove the air, unscrew the gun head 1 to
1½ turns and perform the following:
7.1. Draw back the plunger rod fully and release quickly. Repeat several times. This will exert the force required to move the plunger
into the cartridge (which is essential for the grease gun to work). Push the plunger rod all the way in. Tighten the head to the barrel.
7.2. Press the air vent valve several times to free the air.
Note: If the SA40.V2 is used with cartridges for a long period, it is possible that the rubber plunger may be damaged. If it is, then
if used with dispenser or bulk lling, the plunger may allow grease to seep from the bottom of the container tube. To prevent this
happening, use only one type of ll method for each gun.
PROBLEM CAUSE SOLUTION
Grease gun pumps little or
no grease.
1. Barrel not completely tightened.
2. Air Pockets are trapped in grease.
3. Blocked grease gun extension.
4. Grease too thick or cold.
1. Tighten the barrel completely.
2. Prime grease gun as detailed in instructions.
3. Remove the extension and operate the grease gun. If the gun
dispenses grease then the gun is ne and you need to either
clean the extension or replace it.
4. Store grease gun and grease away from extreme cold or use
thinner grease.
Excessive grease leaking
past the follower.
1. Follower is damaged.
2. Improper seal between the plunger and
the grease gun barrel when using bulk ll or
transfer pump.
Replace the grease gun.
Gun cycles very slowly. Inadequate lubrication of the pumping
chamber.
Put a few drops of lubricator oil through the quick connect
coupler tting.
If the gun still doesn’t operate. Contact nearest authorised service dealer.
