Variable Speed Trigger Switch (Fig. 2, 4)
LOCK-OFF BUTTON AND TRIGGER SWITCH
Your grease gun is equipped with a lock-off button (B).
To lock the trigger switch, press the lock-off button as shown in Figure 4.
Always lock the trigger switch (A) when carrying or storing the tool to
eliminate unintentional starting. The lock-off button is colored red to
indicate when the switch is in its unlocked position.
To unlock the trigger switch, press the
lock-off button as shown in Figure 4.
Squeeze the trigger switch to turn the
motor ON. Releasing the trigger switch
turns the motor OFF.
NOTE: The variable speed trigger switch
will give you added versatility. The further
the trigger is depressed the higher the
output of grease.
WARNING: This tool has no provision to lock the switch in the ON
position, and should never be locked ON by any other means.
Pressure Relief Valve (Fig. 5)
The pressure relief valve (W) is set at
the factory to relieve pressure
above 10,000 psi (690 bar). Grease
coming out of the pressure relief
valve indicates a clog in the fi tting,
line or bearing. Any of these
conditions must be corrected
before proceeding.
