MAINTENANCE
SAFETY RULES
1. Lower load and boom, shutdown engine, remove key and put it in a safe place.
Place warnings on the ignition switch and crane controls to prevent unauthorized
starting or movement during maintenance. Disconnect battery when disabling
crane or when welding on crane.
2. Relieve hydraulic pressure when working on hydraulic parts by cycling the controls
with the engine shut down.
3. Allow fluids and parts to cool before working on them.
4. Read maintenance instructions before beginning work.
5. Do not check for hydraulic leaks with hands. If a mist of hydraulic oil is noticed
around a line or component, use cardboard or other material to check for location
of leaks. High pressure fluid leaking from a small hole, can be almost invisible, yet
have enough force to penetrate the skin. If injured by escaping fluid, see a doctor
at once. Serious reaction or infection can occur.
6. Wear safety glasses and shoes.
7. Do not wear loose-fitting or torn clothing.
8. Remove rings and other jewelry.
9. Wear heavy leather gloves when working on wire rope.
10. Keep clothing and hair away from moving parts.
11. To prevent falls, clean areas of crane that are stepped on for access to crane
parts. Wear slip resistant footwear.
12. Avoid placing body parts in pinch points. Use tools that extend through the pinch
points when possible. Block the moving parts securely when it is necessary to work
in pinch points.
13. When inflating or adding air to a tire, place a tire cage over the tire and use a clip-
on inflater chuck with an extension hose that will permit standing behind the tire
tread when inflating.
14. Do not work on any machine that is supported only by jacks or a hoist. Always use
adequate blocks or jack stands.
15. If it is necessary to work on the boom or outriggers in an unstowed condition, block
them to prevent them from dropping unexpectedly.
