Before Starting the Machine
General
DANGER Before lowering the attachments to the ground, make sure that the machine and the area around
it are clear of other people. Anyone on or close to the machine could fall and be crushed by the attachments,
or get caught in the linkages.
WARNING Secure all loose articles. Loose articles can fall and strike you or roll on the floor. You could
be knocked unconscious, or the controls could get jammed. If that happens you could lose control of the
machine.
CAUTION If the machine has been shut down for a significant period of time with the attachment raised, pilot
pressure may have leaked down to a low level which prevents lowering of the attachment. If the attachment
cannot be lowered without battery power, it will be necessary to start the motor and lower the attachment
before doing the walk-around inspection.
1. Read the Operating in Low Temperatures or Operating in High Temperatures procedures in the Operation
section if you will be using the machine in very cold or very hot climates.
Refer to: Operating Environment (Page 80).
2. Lower the excavator bucket and dozer to the ground, if they are not already there. They will lower
themselves under their own weight when you operate the controls. Operate the controls carefully to control
the rate of descent.
Refer to: Operating Levers/Pedals (Page 53).
3. For your own safety (and others) and for the maximum service life of your machine, do a pre-start inspection
before you start the machine.
3.1. If you have not done it, do a walk-around inspection of the outside of the machine.
Refer to: Walk-Around Inspection (Page 27).
3.2. Remove any dirt and rubbish from the canopy interior, especially around the pedals and control levers.
3.3. Remove any oil, grease and mud from the pedals and control levers.
3.4. Make sure that your hands and shoes are clean and dry.
3.5. Remove or stow all loose articles in the canopy, for example tools.
3.6. Examine the ROPS (Roll-Over Protective Structure) and TOPS (Tip-Over Protective Structure) for
damage. Get your JCB dealer to repair any damage. Make sure all securing bolts are installed and
correctly tightened.
3.7. Check around the canopy for loose or missing bolts, screws etc. Replace or tighten where necessary.
3.8. Check the excavator lever gaiters are not damaged or loose, replace or attach as required with new
fasteners.
3.9. Examine the seat belt and its mountings for damage and excessive wear.
Refer to: Check (Condition) (Page 132).
3.10. Make sure that the following operate correctly: lights, horn, and all switches.
Refer to: Electrical System (Page 141).
4. Adjust the seat so that you can comfortably reach all the driving controls. You must be able to operate the
control pedal with your back against the seat back. Make sure the seat locking lever has fully engaged.
Refer to: Operator Seat (Page 32).
5. Adjust the rear view mirrors (where applicable) to give you a good view close behind the machine, when
you are correctly seated.
6. Fasten the seat belt.
