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.

WARNING: Never attempt to connect or discon- nect the couplers with the hydraulics engaged and the system oil under pressure.

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

72ft.-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
