Make sure that personnel are clear of machine before starting engine, moving out or before lowering or raising bowl.
b.
Keep machine under control at all times. Do NOT coast or overspeed engine.
c.
Avoid driving close to edge of excavations, overhangs, cliffs, etc.
d.
Avoid operating machine on a severe side slope. When possible, operate up and down slopes. Maximum side slope
operation (1st gear forward and reverse) +/- 20% loaded or 35% side slope empty.
e.
Reduce engine speed when maneuvering in tight quarters or when going over a hill. Slow down to negotiate ditches,
potholes, bumps or any other obstructions.
f.
Select appropriate travel speed before driving downhill. Select same gear speed as would be used to travel uphill. Do
NOT downshift while going downhill; downshift BEFORE starting downhill. Do NOT allow machine to overspeed
when going downhill. Apply service brakes.

h.
Never straddle a concertina wire or wire rope cable. Avoid any wire or debris that could become tangled in tires.
i.
Follow these guidelines when operating in soft soil conditions:
(1) Before operating in soft soil conditions, check out site to evaluate its condition. If it appears too soft for even an
initial pass with an empty machine, do NOT enter area. Notify your supervisor.
(2) If site appears to be OK, make an initial pass with an empty machine.
(3) During operation, observe ground conditions. Look for cracking that may appear adjacent to the wheels.
(4) Adjust machine performance for soft soil conditions; make smaller cuts at lower speeds. Do NOT break traction.
