MAINTENANCE AND LUBRICATION

The TORO 007 is designed for hard work in difficult and demanding mine conditions. To
ensure trouble--free and economical operation, it is extremely important to adhere to the
service schedule indicated. By paying close attention to the service schedule, you can
easily detect possible defects in the machine or other problems that can be addressed
before they become serious. This will ensure low repair costs and minimize disturbances
to production.
The following pages give information for servicing various TORO 007 components and
other items for servicing, with their corresponding service intervals. All end users should
review the Engine Manuals for additional information regarding servicing.

2.1. Maintenance of hydraulics

Maintenance, repair, and installation of hydraulic equipment must be carried out only by
experienced hydraulics experts.
Do not attempt any such repairs that you do not fully understand.
D
Never do any repair work on the hydraulic circuit when the system is pressurized.
D
Always stop the engine before tightening or repairing a leaking hose connection.
D
Do not try to locate a leak in a hose or a connection by using your hand. The
D
high-pressure oil spray from the leak can penetrate the skin and cause serious
injury. High-pressure oil spray can also start a fire.
Avoid direct skin contact with oil. Prevent oil from getting into your eyes; use eye
D
protection.
Do not work under a device or component that is held up only by the hydraulics.
D
Use separate supports in conjunction with maintenance and repair.
Do not remove boom cylinders or their valves unless the boom is properly
D
supported and the system non--pressurized.
Pipe connections, hose lengths, and hose types must correspond with the
D
specifications. When replacing or repairing hoses, use original SANDVIK
TAMROCK spare parts or hoses and fittings recommended by the manufacturer.
Ensure that the pressure ratings of the hoses and connecting fittings correspond
with the working pressures.
Any deviations require written authorization from the manufacturer.
D
Pressure tests
General
D The hydraulic oil temperature should be 60...80 _C.
D Connect and disconnect pressure gauge(s) only when the circuit is not
pressurized.
D Use only special couplings for pressure testing.
D Do not over--tighten couplings. When special couplings are used,
finger--tightening is adequate. Over- -tightening leads to harmful leakage.
D Use hose(s) long enough to read the gauge(s) while the operator is sitting in the
cabin.
