Engine Safety
DANGER: Engine exhaust gases contain poisonous carbon monoxide. Carbon monoxide
is odorless and colorless and can cause injury or death if inhaled. Do not use equipment
indoors without adequate ventilation. Refer to OSHA guidelines and regulations
concerning maximum levels of exposure to carbon monoxide gases and other hazards
associated with using internal combustion engines. It is highly recommended that a CO
(carbon monoxide) detector be used to warn the user if levels become unsafe.
Warning: Engine, exhaust system and hydraulic component temperatures could be in
excess of 200F causing severe burns if touched.

The wheels of the machine are controlled by the two outside handles (1 and 3). Pushing both handles forwards,
the machine drives forwards. Pulling both handles backwards, the machine drives backwards. The driving speed
depends on the position of the handles. Pushing the right handle forwards the machine turn to the left. Pushing
one handle forwards and pulling another handle backwards the machine will turns around its axis. Correcting
direction while moving is accomplished by slightly reducing pressure on one handle or the other while moving.
1) Left wheel control handle.
2) Tool positioning control handle.
3) Right wheel control handle.
