CONTENTS - INTRO TO FORKLIFT SAFETY Extend the boom to its maximum length. Then retract the boom slowly until the chain slack allows the chain to rest on the top of the boom. Torque the chains on the front of the boom to 30 ft-lb (40 Nm). Lubricate with 80/90 W oil.
CHECK PERSONNEL WORK PLATFORM SYSTEM Follow the procedure for checking the PWP System as outlined on page 52.

CHECK BOOM SLIDE PADS WEAR AND CLEARANCE
CHANGE AIR FILTER ELEMENT(S)
The boom is equipped with special nylon low friction slide pads between the telescopic sections (see illustration). These are pre-greased and initially worn-in at the factory. Normally greasing is not required, except for maintaining a light film of grease on the pad tracking areas of the boom sections. An exception would be if a boom section has been replaced. Rear Inner
The air cleaner assembly consists of an outer (primary) filter element and an inner (secondary) filter element. An air filter restriction indicator for monitoring the condition of the elements is located in the rubber elbow at the rear of the air cleaner. If the air filter becomes restricted, this indicator turns red to warn the operator that the air cleaner requires service. Push the reset button located at the end of the indicator after replacing the element
NOTE: Before replacing the filter element(s),

Slide Pad Detail
push the reset button on the indicator. Start the engine and run at full throttle. If the indicator does not turn red, do not replace the element(s). The outer element should be replaced only when the restriction indicator turns red. The inner element should be replaced every third time the outer element is replaced, unless the outer element is damaged or the inner element is visibly dirty. Along with a daily check of the restriction indicator, check that the air cleaner intake hose and clamps, and the mounting bracket hardware are properly secure. Inlet Cap
Visually check for loose pad bolts. The bolts are torqued to 30 ft-lb (40 Nm). If the bolts are re-torqued at any time, Loctite® thread lock must be re-applied to the bolts.
Element Cover Clips
If the boom starts to chatter under load, grease the slide pads and wipe off the excess. If a top or side slide pad shows excessive wear, loosen bolts and insert shims to each side or top and bottom for even distribution of clearance. Re-apply Loctite® thread lock to the bolts and re-torque to 30 ft-lbs (40 Nm). Bottom slide pads should be replaced when the thickness is worn down to 3/8” (9.5 mm).
