Head Torsion Spring Removal - DeWalt DW708 Repair Manual

When re-assembling the motor, carefully position the motor cable in the correct
position so that it cannot be trapped.
Note that the two "lugs" on the bearing housing (94) fit into the two larger slots of
the arm casting assy. (102) when putting the motor back onto this housing. (see
drawing "A").
The pulley belt tension is adjusted by the adjusting screw (19) located in the
bearing housing (94).
If the guard or gearcase parts need to be removed proceed as follows :
Release the head lock and guard lock levers to allow the head to come up into the
normal cutting position.
To remove the upper guard casting (105) undo the screws (31) and lift off the
casting, this will now allow you access to the linkage (110) and lower guard (109).
The linkage is removed by undoing the screw (16), then taking off the bush (113).
Remove the screw (27), washer (36), and bush (114) at the other end of the linkage,
and then lift the linkage clear. When re-assembling the linkage ensure that the
roller goes over the "runner" part of the casting (102), and not under it. (drawing "B")
To remove the plastic guard (109) undo the screws (6) and lift off the plate (82),
taking care as the tension of the guard spring (54) will be released as you undo the
screw ! The guard can now be taken off of the machine.
By removing the plate (82) you can now take off the gearcase, and replace any
components inside as required.
When re-assembling the plastic guard, the spring (54) must be located in the hole in
the guard, and the hole in the plate (82). Push the guard and plate up to the
gearcase and turn the plate to position the screw holes to line up with the screw
holes in the gearcase, whilst ensuring that the spring is still located in he holes of
both the guard and plate.

HEAD TORSION SPRING REMOVAL.

Before moving onto the table assembly the motor and head assy. casting (102)
needs to be removed from the bevel housing support (130).
Lock the head down, and then remove the screws (17) that hold the pin (115) in
position. You can now release the head lock after undoing the screws.
Remove the grub screws (13), release the cable clamp (128) from the end cap
housing, this is done by using a pair of pliers to nip the plastic clamp together, and
then pulling the clamp out of the end cap housing (127).
The end cap can be carefully tapped off the bars (12) making sure that you do not
damage either the end cap or bars.
Loosen the screws (15) that fix the guide bushes (123), and slacken the rail lock
lever (126) to allow the bars (121) to be pulled out of the support housing (130).
The complete bar assembly can now be pulled through the support housing.
Once removed turn this assembly over so that it is upside down, enabling you to see
the underneath of the spring(60). It will be easier if you clamp the assembly in a
vice whilst working on this section.
With the screws (17) released you can now knock the pin (115) out of the bracket
(121), (drawing "C") this will release the tension of the spring which can then be
removed together with the plastic bushes (116). Note which way around the plastic
bushes are fitted.
