9.0 ROUTINE MAINTENANCE
WARNING
Avoid contact with escaping hydraulic fluid under pressure. If hydraulic fluid punc
-
tures skin, seek medical treatment immediately. Contact with escaping hydraulic fluid
under pressure could result in serous injury or death.
Inspect all hose, hose fittings and couplings for leakage and damage (see 9.2 routine maintenance for couplings and 9.3 routine
maintenance for hoses).
Using a torque wrench, tighten the socket head cap screws which hold the control valve to the valve manifold and the valve manifold
to the hydraulic cylinder to 180 in/ lbs (20.3 Nm).
CAUTION
DO NOT OVERTIGHTEN! These screws are installed securely at the factory but may loosen
because of vibration while being transported on moving vehicles.
9.1 ANNUAL MAINTENANCE
1. Annual maintenance shall be completed by an Authorized AMKUS dealer while the rescue tool is under warranty.
2. Contact the Amkus dealer or Amkus directly for replacement parts.
3. Always relieve the rescue tool of internal pressure prior to servicing.
9.2 SPREADER ARM MAINTENANCE
Annually at a minimum, or more often if necessary, removal of the spreader arms for cleaning and inspection shall be performed by
either an Amkus Level One Service Technician or a local Amkus dealer. Removal of the spreader arms is most easily accomplished
by opening the spreader arms to the near full open position (as shown below). Personnel doing this inspection shall wear safety
glasses.
1.
Loosen and remove the socket head cap screw which secures the protective rack cover to the rod/rack. Next, remove the flat
washer. Slide the protective rack cover up and off of the rod/rack.
2. Using external retaining ring pliers, remove the retaining rings which secure the spreader arm pivot pins to the spreader bracket
(Photo 1). Discard the retaining rings. Tap out the pivot pins (Photo 2). Lift each arm out of the spreader bracket (Photo 3).
3.
Clean away all dirt and grease. Inspect the spreader arms and the rod/rack for any signs of damage or excessive wear. Pay
particular attention to the gear teeth.
4.
Apply a general purpose white lithium grease such as Lubriplate® NO. 630-AA to the teeth of the spreader rack, the teeth of each
spreader arm, inside the pivot pin holes of each arm, inside the pivot pin holes of the bracket and the surfaces of the spreader
arm that will contact the spreader bracket.
5. To reassemble the spreader. Be sure the gear teeth of the arms engage properly with the gear teeth of the rack. Lubricate and
insert the pivot pins. Install new retaining rings into the grooves at each end of both pivot pins.
6. Clean away all dirt and grease and inspect the protective rack cover for damage. Replace the protective rack cover if damaged.
Reinstall the protective rack cover by sliding it down over the rod/rack. Replace the flat washer. Install and tighten the socket
head cap screw.
