PRIMING THE CONTINUOUS SHOT
GREASE GUN
With the gun loaded with grease and the gun hooked to an air
supply, activate the trigger until grease flows from the hose or
pipe. To relieve air pockets, operate the air vent valve #31
while depressing the trigger. If grease does not flow after
10-15 seconds of operation, remove the hose or pipe and
activate the trigger until grease flows from the hose/pipe
outlet. Make sure the bearing, fitting and lubrication line are
clear and free flowing before operating the gun. If the bearing,
fitting or lubrication line is blocked, the gun can stall.
