Service Interval Of The Combustion Engine; Service Intervals; Wheels - Viking GB 460 Instruction Manual

2 wear limit of wing blades (1):
The measurement procedure and
the value specified are the same for
both wing blades.
Asymmetrical wear may occur at
the two wing blades due to uneven
use of the cutting edges.
Minimum blade width (A) of the two wing
blades (1):
A = 39 mm
3 Wear limit of blades (2):
The blades (2) are reversible
blades. After reaching the specified
wear limit (B), the blade can be re-
sharpened and reversed until the
wear limit is reached, before
needing to be replaced.
● Measure the distance (B) shown in the
illustration from the large diameter of
the bore to the cutting edge (X).
● Repeat this procedure at the second
bore on the blade.
Minimum distance (B) on the blades (2):
B = 6 mm
The particular blade (2) must be
reversed or replaced if one of the
two distances measured is less
than the minimum distance (B).
4 Wear limit of blade (3):
The blade (3) is a reversible blade.
On reaching the specified wear
limit (C), the blade (3) can be re-
sharpened and reversed until the
wear limit is reached, before
needing to be replaced.
● Measure the distance (C) at a right
angle to the cutting edge.
68
Minimum distance (C) on the blade (3):
C = 7 mm
The blade (3) must be reversed or
replaced if the distance measured
is less than the minimum
distance (C).
5 Wear limit of counter-blade (4):
Asymmetrical wear may occur at
the counter-blade (4) due to
uneven use of the cutting edge.
● The counter-blade (4) must be replaced
before the edge (D) at the tip (5) of the
blade is ground down and no longer
visible.
12.10 Service interval of the

12.12 Wheels

The slide bearings of the wheels are
maintenance-free.
Tyre pressure:
1.8 - 2.0 bar
Maintenance interval:
Check and if necessary correct the tyre
pressure of the wheels before using the
garden shredder and after extended
periods when not in use.
Correcting the tyre pressure:
● Unscrew the valve cap (1) from the
valve (2) and set the specified tyre
pressure using a suitable pressure
gauge.
● Screw the cap (1) onto the valve (2).
Checking procedure of the tyre
pressure without a pressure gauge:
If a pressure gauge is not available for
adjusting the tyre pressure, the pressure
can be checked using the control
dimension (Y) from the axle to the ground.
Minimum distance Y = 110 mm
