8.1 Operation
1.
Position all working components and ensure oil connections
are complete.
2.
Adjust air supply to provide required booster pressure.
3.
Booster is activated by pulling handle on the control valve.
When handle is released, the booster retracts via return spring.
Working cylinders or clamps also retract unless a shut-off valve
has been installed to maintain pressure beyond the booster.
9.0 MAINTENANCE
1.
Frequently check booster reservoir sight gauge to ensure oil
level remains at proper level. Small red circle, in sight gauge, is
maximum level.
2.
After system repairs or oil changes, the hydraulics must be bled
to remove trapped air.
(a) Loosen a fitting furthest from the booster.
(b) Activate booster to fully advance the hydraulic plunger.
Tighten the fitting.
(c) Re-fill booster reservoir. If working system components
continue to function erratically or very slow, bleed system,
check for leaks, repair or replace faulty items.
3.
Changing Hydraulic Oil
(a) Change intervals are: every 150 hours during normal
operating conditions, every 50 hours under dirty, dusty or
extremely humid conditions.
(b) Place a drain pan under booster outlet port. Remove
hydraulic line. Tip booster to drain oil into the pan.
(c) Re-install hydraulic line, Remove red fill cap and re-fill
reservoir (1
3
/
4
quart). When oil appears in sight glass red
circle, reservoir is full.
