(Figure 4-2)
Fluid Level
With platform fully lowered i.e. stowed, oil should be
visible on the dipstick. If the oil is NOT visible, fill the
tank until oil (ISO#46) is then visible on the dipstick.
DO NOT fill above the upper line on the dipstick 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.
Wear safety gloves and safety glasses when
handling hot oil (hydraulic oil can be a skin
irritant). The hydraulic oil may be of sufficient
temperature to cause burns.
