Oil Check Procedure
• Lube Point(s) - Hydraulic Reservoir
• Reservoir Capacity: 0.80 Gal. (3 L)
• Lube - Hydraulic Oil
• Interval - Check Daily
NOTE: Be certain the hydraulic oil has warmed to operating tem-
perature before checking the oil level in the reservoir.
1. From either side of the machine, open the side access
door on the base frame (1). Locate the hydraulic oil
reservoir (2) on the pump unit (3). Check the oil level in
the hydraulic reservoir by looking at the markings on
the side of the tank. The reservoir is marked with MIN
(minimum) and MAX (maximum) markings (4). The oil
level must be within these markings to operate properly.
2. If additional oil is required, wipe all dirt and debris from
the filler/breather cap (5) area, add proper grade of oil
by using a funnel with a flexible spout or a plastic
squeeze bottle. Fill until oil level is between the MIN
and MAX markings (4).
NOTE: Care should be taken not to introduce any impurities (dirt,
water etc.) while cap is removed.
NOTE: Recommended lubricating intervals are based on
machine operations under normal conditions. For
machines used in multi-shift operations and/or exposed
to hostile environments or conditions, lubrication fre-
quencies must be increased accordingly.
