WARN I N G
Be ALERT for personnel in the area while operating machine. Always ensure area is clear
of personnel and obstructions before starting engine, moving machine, or lowering or
raising scraper bowl.
Always use a ground guide when moving machine in a confined area.
Do NOT allow riders on machine.
Failure to follow these warnings may result in injury or death to personnel.
General Information.
0005
a. Make sure that personnel are clear of machine before starting engine, moving out, or 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) is 20% (11 degrees) loaded or 35% (20 degrees)
empty.
e. Reduce engine speed when maneuvering in tight quarters or when going over a hill. Slow down to negoti-
ate 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.
g. Do NOT overload machine.
h. Never straddle a concertina wire or wire rope cable. Avoid any wire or debris that could become tangled in
tires.
i.
Adjust apron opening based on material being picked up.
(1) If moving large material or slabs, adjust position of apron so it has a larger opening.
(2) If moving loose or small material, adjust position of apron so it has a smaller opening.
j.
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.
