3. Before starting work, remove the leads from the battery. ALWAYS remove the lead from the negative (-) terminal first.
4. When raising heavy components, use a hoist or crane. Check that the wire rope, chains and hooks are free from damage.
Always use lifting equipment which has ample capacity. Install the lifting equipment at the correct places. Use a hoist or
crane and operate slowly to prevent the component from hitting any other part. Do not work with any part still raised by
the hoist or crane.
5. When removing covers which are under internal pressure or under pressure from a spring, always leave two bolts in
position on opposite sides. Slowly release the pressure, then slowly loosen the bolts to remove.

careful when installing tubes for high pressure circuits. Also check that connecting parts are correctly installed.

guards, or parts which vibrate violently or rotate at high speed, be particularly careful to check that they are installed
correctly.

suddenly, so never let anyone stand at either end of the track.
15. When jump starting the machine, only use a machine of similar size and voltage. Never use a arc welder or other electrical
generating equipment to jump start the machine. Carefully review the safety and procedures for jump starting the
