service. Refer to the appropriate sections for lubrication
information on the Steering Linkage, Torque hubs,

GREASE FITTINGS
Wipe each grease fitting before and after greasing.
Using multipurpose grease in a grease gun, pump the
grease into the fitting until grease just begins to appear
at the edges of the pivot, wipe off any excess grease.
HYDRAULIC OIL AND FILTER
Fluid Level
With the platform fully lowered, check oil level on sight
gauge. If the oil is NOT in operating range, add hydrau-
lic fluid until oil is visible in operating range on dipstick
or visible in sight gauge. DO NOT fill above operating
range or when the platform is elevated.
Oil and Filter Replacement
1. Operate the platform for 10-15 minutes to bring the
hydraulic oil up to normal operating temperature.

the gasket makes contact then rotate 3/4 of a turn
further.
