This kit includes control valves, hoses and quick connect
couplers for supplying hydraulics power to optional
attachments. When not in use, the coupler dust covers must be
in place to prevent contamination. Always replace them
immediately if damaged or lost. Note the hydraulic circuit
connectors called out in Figure 3-18.
Once connected, the operator has control of the
attachment's hydraulic cylinder by means of the valve control
levers. If stroking the valve lever produces the wrong cylinder
movement (up-down, right-left, etc.), reverse the attachment
hoses at the quick connect couplers. Use of the valve control
lever varies with each attachment and is described in more
detail in the operating instructions provided with the
attachment.

Rear counter-balance weights

WARNING: Improper operation on slopes can
cause injury. Install rear counter-balance weights,
when the attachment is installed, to increase stabil-
ity. Use extreme care when operating on slopes.
Rear counter-balance weights are required to improve
stability, steering and traction. They also reduce tire lift off
when attachments are raised, operated on slopes or during an
abrupt stop. Refer to Figure 3-19 for weight attachment.
Refer to the attachment's owner's manual for the proper
weight amount and weight part number.

ROPS
(Roll Over Protective Structure)
A Roll Over Protective Structure (ROPS) and seat belt are
standard equipment. Do not remove the ROPS and seat belt.
ROPS when used with seat belt is effective in reducing
injuries during unit overturn accidents. Overturning the unit
without ROPS can result in serious injury or death.
NOTE: Inspect the ROPS after the first 20 hours of opera-
tion. Following the initial inspection, check the ROPS after
every 500 hours of operation or every six months, whichever
comes first. Figure 3-20
1. Check the torque of the ROPS mounting bolts. Tighten
the bolts to the correct torque of 72 ft.-lbs. (97 Nm) if
necessary. Figure 3-21
2. Inspect the operator's seat and the mounting parts for
the seat belt. Tighten the bolts to the correct torque of
72 ft.-lbs. (50.0 Nm) if necessary and replace parts that
show wear or damage.
The two-post ROPS can be pivoted down by removing the
right and left retaining rings and pulling out on the pins so that
the machine can operate under low hanging tree limbs or
other obstructions. (Figure 3-22) Do not wear the seat belt
