Section 1 Safety Rules
Most accidents are the result of negligence and careless-
ness, usually caused by failure of the operator to follow
simple but necessary safety precautions. The following
safety precautions are suggested to help prevent such
accidents. The safe operation of any machinery is a big
concern to consumers and manufacturers. Your Clutch
Linkage Update Kit have been designed with many built-
in safety features. However, no one should operate this
product before carefully reading this Operators Manual.
General Operation & Repair
1. DO NOT exceed 20 mph transport speed.
2. Areas of this drill can be dangerous and can cause bodily
harm if not properly used or guarded. Stay away from
equipment when it is in operation!
3. Before working on, servicing or making adjustments on
the drill, ALWAYS disengage power, shut off engine,
make sure all moving parts have stopped, and all pres
-
sure in the system is relieved.
4. Escaping fluid under pressure can have sufficient force
to penetrate the skin. Check all hydraulic lines and hoses
before applying pressure. Fluid escaping from a very
small hole can be almost invisible. Use paper or card
-
board, not body parts, to check for suspected leaks. If in-
jured, seek medical assistance from a doctor that is
familiar with this kind of injury. Foreign fluids in the tis
-
sue must be surgically removed within a few hours or
gangrene will result.
