SERVICING SAFETY PRECAUTIONS continued SAFE REMOVAL OF STABILIZER COUNTERBALANCE AND CHECK CARTRIDGES
WARNING Keep your hands, feet, head, and loose clothing away from power driven parts. Tie long hair behind your head. Remove rings and other jewellery to prevent electrical shorts and entanglement in moving parts.
When the stabilizers are on the ground, Hydraulic oil in the cylinders can be under very high pressure. Never remove the check valve or the counterbalance cartridges when the stabilizers are on the ground.
Always be aware of machine pinch points that could cause injury. Never place body parts within the range of motion of the working parts of the machine.
If it becomes necessary to remove either the stabilizer counterbalance or check cartridge from the housing, or cylinder base end on earlier machines; Raise the stabilizer until it is in the "overcenter" position and stop the engine. In this position, the weight of the stabilizer will not influence pressures in either end of the cylinder. VERTICAL CENTERLINE
LOWER FRAME
Never stand under an object supported with hydraulics. Always use safety stands or a locking device. Before performing work on the grapple or boom, ensure they are firmly supported.

If the engine is running inside a building, ensure that sufficient ventilation is available to prevent a buildup of toxic exhaust fumes. Run the engine only when it is necessary for testing or adjustments.
STABILIZER COUNTERBALANCE/CHECK VALVE CARTRIDGE REMOVAL
230-06A
Work in a ventilated area. If it is necessary to run an engine in an enclosed area, use an exhaust pipe extension to remove toxic exhaust fumes.
If a stabilizer cannot be moved to the vertical position due to a malfunction, move the other stabilizers in conjunction with the boom so that the stabilizer pad is clear of the ground. In this position the pilot operated check valve may be removed followed by the counterbalance valve.
If you don't have an exhaust pipe extension, either work outside, or open the shop doors.
