Hydraulic Pressure Gauge Connection
ONLY OPEN HYDRAULIC SYSTEM LINES WITH THE MAST FULLY
LOWERED TO RELIEVE PRESSURE IN THE SYSTEM. CAREFULLY
LOOSEN REQUIRED FITTINGS, WEAR SAFETY PROTECTION
EQUIPMENT WHEN WORKING WITH HYDRAULIC SYSTEMS.
NOTE: See Section 5.5, Hydraulic Line - Disconnect - Spe-
cial Tool, for hydraulic line removal procedure.
Remove the hydraulic oil filter and install a t-fitting
between the pump and the extend line to connect a
hydraulic pressure gauge as shown in Figure 1-2., Typical
Hydraulic Pressure Gauge Installation (Hydraulic Filter
Removed).
CHECK, and if necessary, ADJUST the hydraulic pressure
to initial settings shown in table at the beginning of this
section. Cycle the hydraulic system several times with the
maximum load capacity in the platform, then recheck
pressure setting. When pressure has stabilized continue
to "After Filter Pressure Check" following.
After Filter Pressure Check
Reinstall the hydraulic oil filter and install a t-fitting
between the hydraulic filter and the extend line to the cyl-
inder. Recheck the hydraulic pressure and compare with
the previous readings when filter was removed. If a signifi-
cant drop in pressure reading has occurred, replace the
hydraulic filter and recheck the "after filter" pressure read-
ing.

NOTE: All dimensions are given in inches (in), with the met-
ric equivalent, centimeters (cm), given in parenthe-
ses.
1.8 SERIAL NUMBER LOCATIONS
For machine identification, a serial number plate is affixed
to the machine. The plate is mounted on the base frame
between the front caster wheels under the front cover. The
serial number is also stamped on the front of the mast
assembly near the amber beacon.
