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. Disconnect
battery, RCL and engine electronic module 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 fingers, 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. Use appropriate ladders/steps to gain access to boom tip and
deck.
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
point areas.
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. Use proper tire handling equipment when changing any tires of this size.
14. Do not work on any machine that is supported only by jacks or a hoist. Always use ade-
quate blocks or jack stands.
15. If it is necessary to work on the boom in an unstowed condition, block it to prevent it from
dropping unexpectedly.
