Hydraulic Oil Check Procedure
Lube Point(s) - Hydraulic Reservoir
Reservoir Capacity - See Table 5-8 on page 5-7.
Lube - Hydraulic Oil
Interval - Check Daily
NOTE:
Check the hydraulic oil level with the platform in the
stowed position ONLY. Be certain the hydraulic oil has
warmed to operating temperature before checking the oil
level in the reservoir.
1.
On the left side of the machine, remove the
side
access door on the base frame
. Locate the
hydraulic
oil reservoir (1)
on the
pump unit (2)
. Check the oil
level in the hydraulic reservoir by looking at the mark-
ings on the side. The reservoir is marked with a
MAX
(maximum) marking (3)
. The oil level must be kept at
or within one (1) inch of this marking to operate prop-
erly.
2.
If additional oil is required, wipe all dirt and debris
from the
filler/breather cap (4)
area, add proper
grade of oil. Fill until oil level is close to the
MAX
marking (3),
but not over the
MAX marking
.
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.
