Maintenance And Repairs - Viking GB 370 S Instruction Manual

The operator must stand in the working
area described when feeding the
shredder. Stay inside the working area and
outside of the ejection zone at all times
during operation of the machine. (
Risk of injury:
Shredding material may be ejected back
up during operation. Always wear safety
glasses and keep your face away from the
feed opening.
Never tilt the machine when the engine or
motor is running.
If the machine falls over during operation,
immediately switch off the engine and
detach the spark plug socket.
Make sure that there is no shredding
material blocking the ejection chute, as
this could result in a poor shredding
performance or kickbacks.
When feeding the garden shredder, pay
particular attention to ensuring that no
foreign objects such as bits of metal,
stones, plastic, glass, etc. get into the
shredding chamber as this could result in
damage or kickbacks from the feed chute.
Remove blockages for the same reason.
Kickbacks can occur when feeding the
garden shredder with branch material.
Wear gloves.
Stop the engine
– before tilting, pushing or pulling the
machine,
– before unscrewing the closure screws
and opening the machine,
– before re-filling the tank. Allow the
engine to cool down before re-filling the
tank.
Fire hazard!

the spark plug socket and allow
all rotating tools to come to a complete
standstill
– before leaving the machine unattended
– before lifting or carrying the machine
– before transporting the machine
– before removing blockages at the
cutting unit, in the feed chute or in the
discharge chute
– before working on the cutting unit
– before checking or cleaning the
machine or before carrying out any
other work on it.
If foreign objects get into the cutting tool or
if the machine makes strange noises or
vibrates in an unusual way, switch off the
engine immediately and allow the machine
to come to rest. Detach the spark plug
socket, remove the feed chute and
perform the following steps:
– check the machine, in particular the
cutting unit (blade, blade disc, blade
fastening screw) for damage and have
any necessary repairs carried out by a
technician before restarting and
working with the machine.
– check that all parts of the cutting unit
are seated securely, retighten the
screws if necessary (observe tightening
torques).
– Have damaged parts replaced or
repaired by a technician; the parts must
be of similar quality.

4.7 Maintenance and repairs

Before beginning cleaning, adjustment,
repair and maintenance operations:
● Park the machine on firm and level
ground
● Stop the engine and allow it to cool
down
● Detach the spark plug
socket.
Caution – risk of injury!
Keep the spark plug socket
away from the spark plug; an inadvertent
ignition spark can result in fires or electric
shocks.
Inadvertent contact between the spark
plug and the spark plug socket can result
in unwanted starting of the engine.
Allow the machine to cool down before
working on or around the engine, exhaust
manifold or muffler in particular.
Temperatures of 80° C and above can be
reached. Danger of burns!
Direct contact with engine oil can be
dangerous. Engine oil must not be spilled.
VIKING recommends leaving the task of
topping up engine oil or performing engine
oil changes to a VIKING specialist dealer.
Cleaning:
The complete machine must be cleaned
thoroughly following use. (
Never use high-pressure cleaners and do
not clean the machine under running water
(e.g. using a garden hose).
Do not use aggressive cleaning agents.
These can damage plastics and metals,
impairing the safe operation of your
VIKING machine.
