31. HANDLING AUTO-GREASING SYSTEM
2. Injector (SL11)
1) The injector is operated by the pressure from the pump, and
it feeds grease of the specified quantity to the bearing.
2) To see if the injector works normally, check the operation of
indicator pin 4 on its head. If the injector is normal, the pin
is retracted first. If the pump stops and the pressure is lost,
the pin returns and it is reset for the next greasing.
3) Adjust the discharge from the injector with adjustment screw
6 on its head.
1) To reduce the discharge, loosen lock nut 5 and turn
adjustment screw clockwise. If the adjustment screw
stops (at the stopper), the discharge is minimized.
2) If the adjustment screw is returned by 10 turns from the
fully tightened position (minimum discharge) in 1] above,
the discharge is maximized (8.2 cc/st).
After adjusting the discharge from the injector, be sure
to tighten lock nut.
4) Although the injector can be overhauled and repaired, re-
place it with a spare one, if possible, when it has any trouble.
‡ Discharge adjusting procedure for large-sized injector (SL-
11) (Added to bucket pin)
Loosen lock nut 5 and turn adjustment screw 6 to adjust the
discharge of grease made each time.
One turn between the maximum and minimum positions change
the discharge by 0.82 cc. After adjusting the discharge, be sure to
tighten the lock nut.
