Lubrication
For those parts pointed out in the Walk-Around Inspection
requiring lubrication, refer to the Lubrication Chart, Table
2-1., for specific time interval requirements.
Hydraulic oils must have anti-wear qualities at least to API
Service Classification GL-3, and sufficient chemical stabil-
ity for mobile hydraulic system service. JLG Industries,
recommends Mobilfluid 424 hydraulic oil, which has an
SAE viscosity of 10W-30 and a viscosity index of 152.
For cold weather applications, i.e. when temperatures
remain consistently below +20°F (–7°C) JLG recom-
mends using Mobil DTE 13 hydraulic oil.
2.5 DAILY FUNCTIONAL CHECK
TO AVOID INJURY DO NOT OPERATE A MACHINE UNTIL ALL
MALFUNCTIONS HAVE BEEN CORRECTED. USE OF A MALFUNC-
TIONING MACHINE IS A SAFETY VIOLATION.
Once the Walk-Around Inspection is complete, a Func-
tional Check of all systems should be performed in an
area free of overhead and ground level obstructions. Per-
form a Functional Check in accordance with the following
procedures:
Set-up machine for operation, according to instructions in
Section 4-3, “Machine Operation”.
NOTE: 20VP MODELS WITH UNDERWRITERS LABORA-
TORY (EE) RATING OPTION ONLY, include a mas-
ter ON/OFF switch located on top of the rear cover of
the machine. This control must be set to the ON
position before the following function checks can be
completed.
