OPERATION

 

 

 

CAUTION

 

Check the tightening of bolts, referring to the tightening torque chart 

The safety is one of our main worries when designing and manufacturing this machine. Negligence in 

the use of the machine spoils our efforts. The prevention strictly depends on the care and on the skill 

of the user when applying and maintaining the machine. The best safety method remains a careful 

and skilled user ; we hope you to be this kind of user. 

 

The user of this machine is responsible for its safe use. He must be a skilled user specially trained for 

the use of this machine. Read the safety instructions. This machine has been designed to mow grass. 

It is not designed for any other operation. It is not designed to transport other tools or materials that 

might damage it and cause injuries to the user. It must not be used to carry persons. 

 

 

DANGER

 

Never use the machine without having priory carried out all the maintenance operations as 

described in the daily maintenance chapter. 

 

 

CAUTION

 

Never let children or unskilled persons use the machine. Check that nobody or no objects 

stands near the machine when at work. They could be hit by the moving parts. Nobody must 

stand on the machine except the driver. Never put your hands under moving parts. 

 

STARTING

 

OF

 

THE

 

ENGINE 

 Turn the fuel cock to "ON". 

 Check that cutting blade is disengaged, and Driving lever range is in neutral position « N ». 

 Push choke lever if engine is cold or push throttle lever half of his stroke if the engine is hot. 

 Pull the starter rope. 

 When the engine has started, pull back the choke lever. 

 Select a speed ratio and travel to the mowing path. 

 

DRIVING

 

ON

 

SLOPE

S

 

Driving on a slope is very dangerous. For your safety, 

never work on  a  more than  15

°

(HRC663) / 25

°

(HRC673 / 813)  slope.  Also,  be careful even when 

you work on a slope of less than the limited degree. 

The unit might tip over depending on field condition. 

 

 Ii

 

Basically, drive up or down.  

In case of driving across the slope, it is safe to turn 

from low level to high level(Figure 7). If machine is 

turning from high level to low level, it is difficult to turn 

properly and it is very dangerous.  

 

 

WARNING

 

It is very dangerous to disengage the driving clutch on slopes unnecessarily or to shift the 

change lever into neutral position.
