 When the machine descends a slope at high speed,
machine weight accelerates descending speed. It may
cause collision accident due to misjudging of braking
distance or machine turnover due to running on an
unexpected obstacle.
Before descending a slope, always ensure that engine
control lever (1) is in the slow idle position, and then
reduce the engine speed. Turn the travel mode switch (2)
to slow speed for ZX26U-5A.
 Be sure to thoroughly warm up the machine before
ascending 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
forward 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
using 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
possible damage to the machine.
 Avoid operations that may damage the track and
undercarriage components.
 During freezing weather, always clean snow and ice from
track shoes before loading and unloading machine, to
prevent the machine from slipping.
