element and clean the magnet in the tank after every 1000
operating hours or if the oil has become contaminated or
after any major hydrostatic drive system repair.

Lower the boom arms, shut off the engine and
engage the parking brake.

Remove the magnetic drain plug located at the
bottom of the hydraulic oil reservoir. Clean any metal
particles that may be attached to the magnet. (fig. C4446)
Have containers ready to hold approximately 8 gallons
(30 liters) of fluid. Replace the drain plug using teflon
sealing tape or liquid type sealant on the plug threads.

Access the suction screen element in the hydraulic
reservoir by removing the inspection cover on the
reservoir, located in the engine compartment. (fig. C1871)
Clean the excess silicone from the cover and reservoir.
NOTE: You may need to remove the control cables and
hydraulic hoses to gain access to the inspection cover
nuts.

Remove and clean the magnet attached to the suction
element. (fig. C3663)

Install the magnet onto a new suction element and
install the suction element.

Seal the inspection hole and install the inspection
cover to the reservoir. Do not over tighten the mounting
nuts. Maximum torque is 15 ft lbs (20.3 N.m.).
