SWDM40 OPERATION & MAINTENANCE MANUAL
211
 If oil is too low, oil viscosity will be increased, the loss of pressure will be
more, and oil will flow slowly affecting the flow of resistance hole and
extending the time of motion, thus, the machine will be sluggish, even will not
able to work.
 When oil temperature is over then 80
℃
, stop operation to idle the machine
cooling down. When starting the machine at -20℃, power on and idle the
Rotary drive for a while, then operate it after the oil is heated up.
Note for Hydraulic System Maintenance
：
 Pressure and flow parameter of hydraulic components have been set before
machine delivered from the factory, forbid to change that. If adjustment is
necessary, professional personnel are needed for that.
 After initial start-up or disassembly for repair, air will exist in the hydraulic
pipeline, power on the machine to idle and make cylinders to move within the
maximum stroke repeatedly to exhaust air, and loosen pipe joint if necessary.
 When the reduction gearbox is rotating, brake it with the balance valve instead
of itself. Failure to comply may result in the burn of reduction gearbox friction
plate and lead to the damage of reduction gearbox.
 Forbid to step on hoses and materials, failure to comply may result in hose
joints damage or looseness, hose crack and lead to oil leakage.
 When replacing hoses, figure out the type and load capacity of hoses. Don’t
replace low-pressure hoses with high-pressure hoses to prevent hose breakage.
Don’t use hoses with small diameter with the larger ones, failure to comply
may increase pressure loss for the pipeline, reducing the work efficiency of
drilling machine.
 Hoses and joints on the rotary drilling rig are sealed by O-ring. Press plate,
joints and nuts should be fastened, as looseness will result in the damage of
seal ring and oil leakage. Check joints and fixed screw for looseness regularly.
8.10.10 Use of Battery
Warning！
 Vapor and explosion of battery may result in personal injury.
 Battery may release flammable vapor which is easy to cause explosion.
 Electrolyte is a kind of acidoid, which may result in personal injury when
it contacts with skin or eyes.
 Avoid spark near to battery, as that will cause explosion.
 Don’t allow jumping cable end touching mutually or with engine, as for
incorrect cable connection may result in explosion.
 Protective goggles should be put on when working on the battery.
