IMPORTANT: Prevent damage to hydraulic system
components. DO NOT run engine
without oil in the tank.
Avoid mixing different brands or types
of oils. Oil manufacturers engineer their
oils to meet certain specifications and
performance requirements. Mixing
different oil types can degrade lubricant
and machine performance.

2. Position machine with arm cylinder fully retracted and
bucket cylinder fully extended.
3. Stop engine.
CAUTION: High pressure release of oil from
pressurized system can cause serious burns or
penetrating injury. The hydraulic tank is
pressurized. DO NOT remove hydraulic cap.
