NB! It is very important that the breaking bolts have a smooth contact surface at the

breaking point, i.e. to avoid that the threaded part is included in the breaking point since

this significantly weakens the breaking strength.

It is the driver's responsibility not to expose himself or others to danger during the use of the snow

blower. Attention should be paid to people and animals located near the machine. Since other

objects occur in the snow (rocks and similar things), the throwing route must be set so that the

draft snow would not be danger to other road users. Since there are more objects in the snow

(stones), the ejection nozzle must be adjusted so that the ejected snow does not pose a danger to

other road users.

No one should ever stand on the machine while it is driving or moving. Protective covers must

always be on when it is used.

The Norwegian Labor Inspection Authority has listed snow blowers among machines that must be

used with particular care and must therefore not be operated by people without documented

training. The user must have a driving license for a tractor (aged 16) and have a certificate that he

has received training in the use of the machine/tool.

The machine requires skilled operation, the user manual must be read before connecting to the

tractor and putting it into operation, even if the user had previous experience with a similar

machine – this is for user's safety.

The top brace is adjusted so that the snow blower is parallel to the ground in working position.

Skid pads must always be used and adjusted according to the instructions in user manual.

Optional use of support wheels.

The direct-coupled PTO must not be switched on at high rpm.

Driving in packed snow, it is important to keep the rpm. high from the time you enter the snow until

the fan is empty.

This happens in the reverse order of connection.

The tractor's PTO must be disconnected when working with the machine and the PTO shaft.

Place the machine on the even ground.

Disconnect hydraulic hoses.

Disconnect the power transmission shaft and hang it on a hook attachment.

Locking bolts for drawbars are released.

Now the machine is disconnected and can be left.
