Hitachi Zaxis 850LC-3 Operator's Manual page 22

• Driving across the face of a slope or steering on a slope
may cause the machine to skid or turnover. If the direc-
tion must be changed, move the machine to level ground,
then, change the direction to ensure safe operation.
• Avoid swinging the upperstructure on slopes. Never at-
tempt to swing the upperstructure downhill. The machine
may tip over. If swinging uphill is unavoidable, carefully
operate the upperstructure and boom at slow speed.
• If the engine stalls on a slope, immediately lower the
bucket to the ground. Return the control levers to neutral.
Then, restart the engine.
• Be sure to thoroughly warm up the machine before as-
cending steep slopes. If hydraulic oil has not warmed up
sufficiently, sufficient performance may not be obtained.
• Use a signal person when moving, swinging or operating
the machine in congested areas. Coordinate hand signals
before starting the machine.
• Before moving machine, determine which way to move
travel pedals/levers for the direction you want to go.
When the travel motors are in the rear, pushing down on
the front of the travel pedals or pushing the levers for-
ward moves the machine forward, towards the idlers.
An arrow-mark seal is stuck on the inside surface of the
side frame to indicate the machine front direction.
• Select a travel route that is as flat as possible. Steer the
machine as straight as possible, making small gradual
changes in direction.
• Before traveling on them, check the strengths of bridges
and road shoulders, and reinforce if necessary.
• Use wood plates in order not to damage the road surface.
Be careful of steering when operating on asphalt roads in
summer.
• When crossing train tracks, use wood plates in order not
to damage them.
• Do not make contact with electric wires or bridges.
• When crossing a river, measure the depth of the river us-
ing the bucket, and cross slowly. Do not cross the river
when the depth of the river is deeper than the upper
edge of the upper roller.
• When traveling on rough terrain, reduce engine speed.
Select slow travel speed. Slower speed will reduce pos-
sible damage to the machine.
• Avoid operations that may damage the track and under-
carriage components.
• During freezing weather, always clean snow and ice from
track shoes before loading and unloading machine, to
prevent the machine from slipping.
