Precautions With The Battery
• When repairing the
electrical system
when performing
welding, remove the
negative (-) terminal of
the battery to stop the
flow of current.
Handling High Pressure Hoses
• DO NOT bend high-pressure hoses or hit them
with hard objects. DO NOT use any bent or
cracked piping, tubes or hoses. They may burst
during use.
• Always repair any loose or broken hoses. Fuel
and/or oil leaks may result in a fire.
Precautions With High Pressure Oil
• Always remember that work equipment circuits
are always under pressure.
• DO NOT add oil,
maintenance or inspections before completely
releasing the internal pressure.
• Small, high pressure pin-hole leaks are extremely
dangerous. The jet stream of high-pressure oil
can pierce the skin and eyes. Always wear safety
glasses and thick gloves. Use a piece of
cardboard or a sheet of wood to check for oil
leakage.
• If you are hit by a jet of high-pressure oil, consult
a doctor immediately for medical attention.
