MACHINE OPERATION
4-29 SY155U Excavator OMM
• Keep the engine running at a low speed.
• Choose low-speed travel mode.
• Operate slowly and observe the motion of the
machine.
• Do not attempt to travel on a slope with the bucket
loaded or with a load lifted.
• Never attempt to travel up or down a slope with a
grade greater than 30°. Never attempt to cross a
slope with a grade greater than 15°.
• Always keep the seat belt fastened.
• Keep the bucket pointed toward the traveling
direction and 16 in. – 20 in. (40 cm – 50 cm) off the
ground. Travel at low speed.
• Do not attempt to change direction on a slope, or the
machine may slip and tip over. Only perform a
direction change on an even and solid surface.
• If the engine stalls on a slope, lower the bucket to
the ground immediately, neutralize all control levers,
and restart the engine.
• For proper machine operation while traveling up a
steep slope, allow the engine and hydraulic system
to warm up to operating temperature.
• Avoid crossing inclines as much as possible.
Slipping or rolling over may occur.

• Do not swing the upper structure to the downhill
direction; the machine may tip over. If such an
operation is necessary, carefully swing the upper
structure and the boom.
• Do not swing a loaded bucket to the downhill
direction. Build a platform (1) on an incline so the
machine can be operated on a level surface.

• When traveling down a grade greater than 15°, the
work equipment should be positioned in front of the
cab. Keep the boom-arm angle between 90° and
110° (1) and the bucket 16 in.–20 in. (40 cm–50 cm)
(2) above the ground.

(40 cm–50 cm) (2) above the ground.
NOTE: When traveling up a grade, make sure the
sprockets are in the downhill direction. If the
sprockets are not in the downhill direction, the
tracks may loosen and result in slippage damage
or misalignment.
