Poweramp POWERSTOP AUTO 11.1996 - Manual (Page 15)

MAINTENANCE
1. Good housekeeping practice is the most commonly needed truck re-
straint requirement. Shipping and receiving docks are notorious for having
wood scraps, steel banding and other debris laying at the front of the
dock. Daily patrol truck restraint area and clean up dock.
2. Depending on the type of application, the Automatic Truck
Restraints usually require lubrication every three months. Lubricate back
track with an anti-seize lubricant. Lubricate linkage with 30 wt. oil.
3. IMPORTANT: Inspect daily and test the inside and outside signal lights.
THEY MUST WORK. Replace broken light bulb as required.
4. Repair or replace signs if required.
5. IMPORTANT: Truck restraint must be protected by dock bumpers.
Worn, torn, loose or missing bumpers must be replaced. Contact your
local Poweramp representative for replacement bumpers.
6. Perform operational tests after all repairs and adjustments.
7. Check hydraulic fluid level with restraint raised. Put selector/power
switch in "off" position. Remove breather from tank. Oil should be
approximately one (1) inch from top of tank.
