SAFETY

Wear safety boots, face mask, shatterproof glasses, helmet, 
gloves and any other personal protective equipment required 
for the working conditions. Avoid loose clothing; this may 
become trapped in moving parts and cause serious injury.
To avoid nuisance dust, connect an industrial vacuum cleaner 
(minimum 3000watts or equivalent) to the 50mm (2”) vacuum 
port situated at the rear of the machine.

Ensure that the workplace is well ventilated. Avoid operating 
engine-powered machines in an enclosed area, since engine 
exhaust gases are poisonous.

Be very careful with hot components. The exhaust and other 
parts of the engine are hot during operation and can remain 
hot for some time after shutdown.

Do not refuel the engine while the engine is hot or running, 
there is a very real danger from explosion – always refuel 
when the engine is cold, and in the open air.
During transportation fasten fuel cap tightly and close fuel tap.

Do not operate electric versions in wet conditions.
Caution this machine is heavy. It weighs between 
(92kg/202lbs) and (144kg /317 lbs) dependent on power unit.
Do not lift this machine manually.

WARNING! Always observe safe-working practices at  
all times.
