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 operat-
ing temperature 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 (mini-
mum) and MAX (maximum) markings (4)
. The
oil level must be within these markings to oper-
ate 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 flexi-
ble 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 impuri-
ties (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 frequencies must be increased accord-
ingly.

CYLINDER SPECIFICATIONS
NOTE:
All dimensions are given in inches (in), with the met-
ric equivalent, centimeters (cm), given in parenthe-
ses.
1.4
TORQUE REQUIREMENTS
When maintenance becomes necessary or a fastener has
loosened, refer to the applicable Torque Chart in this sec-
tion of the manual to determine proper torque values for
various size fasteners.
1.5
SERIAL NUMBER LOCATIONS
For machine identification, a metal serial number plate is
affixed to the machine. The plate is mounted behind the
left rear wheel on the side of the base frame. The machine
serial number can also be found on a bar code label
placed on the platform control station mounting plate in
the platform.
