BEWARE OF HOT FLUID. CONTACT WITH HOT FLUID MAY CAUSE
SEVERE BURNS.
All machines are equipped with a bypassing filter where the hydraulic fluid returns to
the tank (see Figure 1-2). When the filter is clogged, hydraulic flow bypasses the filter
element. The filter element must be changed every six months or 300 hours. Extremely
dirty conditions may require the filter to be replaced more often.
To replace:
• Unscrew the filter assembly cap, then remove the filter
• Place the new filter into position and press firmly into place
• Carefully thread the filter assembly cap, then hand-tighten only.
