Changing gear with the DS-TS 30 (-54 and 45)
The PH 3/4 hydraulic hoses should be connected before fitting the blade. Use the 36 mm AF open-end wrench
(item no. 258306/0) to rotate the saw blade drive flange until the hole mark
is in the central position
(on
the saw arm centreline). Insert the hex. wrench with T-grip (item no. 221191/0) in the bore in the blade mount-
ing flange
.
Observe the markings on the blade guard holder
.
To engage a gear from the neutral position (between 1
st
and 2
nd
gear) proceed as follows:
– Low (1
st
) gear = push the wrench in and turn it to the right
as far as it will go
.
– Low (2
nd
) gear = allow the wrench to move out under spring pressure and then turn it to the left
as far as
it will go
.
If a gear is already engaged:
– Disengage the gear by turning the wrench to the neutral position. Depending on the gear to be selected, either
push the wrench in or allow it to move out under spring pressure and then turn it in the desired direction as
far as it will go.
IMPORTANT:
When changing from one gear to the other,
the T-grip wrench must be rotated through 180°
(
1
/
2
turn),
i.e. turned as far as it will go, to the right
or to the left
. Running the saw with the gear selec-
tor in the “neutral” position may cause damage to the gearing.
Direction of rotation of the motor or saw blade.
Maintenance
Keep the gear change mechanism clean and lubricate it with Hilti spray at weekly intervals.
