requirement. Shipping and receiving docks are notorious for having wood
scraps, steel banding and other debris laying at the front of the dock.

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 representative for replacement bumpers.
