WATER PUMP MAINTENANCE
When the machine has not been used for a long period of
time, hard packed dirt may begin to build up inside the pump
and block the pump wheel. If the machine is activated with
the immersion pump blocked, the electric motor of the pump
will be damaged within a few minutes! Please follow the
steps listed below to clean the pump before operating the
saw:
1. Remove the immersion pump from the water container.
2. Clean the immersion pump.
3. Loosen the fixing screws of the pump lid.
4. Take the lid off the pump. Be careful not to damage or
lose the gasket underneath.
5. Clean the pump lid.
6. Remove all dirt and incrustations from the pump wheel.
7. Check whether the pump wheel can be easily turned.
8. Then reassemble the immersion pump correctly and
check whether it works properly.
CARBON BRUSH REPLACEMENT
1. Unplug the saw before proceeding any further.
2. Locate the carbon brush caps found on the left and right
side of the motor housing. Remove the caps (turn
counter- clockwise to unscrew) to allow the carbon
brushes to spring out. (See figure 8) If they do not come
out after the caps are removed, use a flat screw driver to
gently nudge them out.
3. When installing the new brushes, make sure they fit
snugly into the slots. Do not modify the replacement
brushes (i.e. file them down) or use non OEM brushes,
as it may damage the armature and in doing so voids the
manufacturer warranty.
4. Perform steps 1 through 3 in reverse to reinstall the fan
cover.
REALIGNMENT
Method 1:
This procedure deals with the most common source of
misalignment that occurs when the guide rails are not parallel
with the blade.
1. Set the cutting depth such that the blade passes through
the table, not over.
2. Place a straight edge (i.e. carpenter’s square) on the
cutting table as shown in figure 9.
3. Loosen the left and right guide rails by loosening the
fasteners found at the ends of the rail. (see figure 9) The
left rail should be slightly loose, so there is not too much
play during adjustments, but the right rail should move
freely as it will be adjusted last.
4. Make sure the short portion of the straight edge is placed
flush against the ruler guide. Adjust the left guide rail so
that the front and rear edges of the blade touch the straight
edge, although a tolerance of 0.1mm between the front
and rear edges is allowed. Perform this adjustment along
the entire length of the straight edge.
5. Position the table as close to the user as possible. Place
the straight edge flush against the ruler guide and blade.
Without holding onto the straight edge, gently move the
table towards the rear of the saw and then back. Observe
any gaps that may appear between the straight edge and
blade or between the straight edge and ruler guide. A gap
exceeding the allowed tolerance means that the table is
not moving parallel to the blade; hence, further
adjustments as outlined in step 4 will be required.
However, if scenario A or B described below occurs, other
adjustments may be required instead.
A.
If the straight edge only touches the blade when the
table is positioned midway along the rail or at the
ends of the rail, then the rail may be deformed (i.e.
bowed). (see figure 10) Perform test cuts to
determine if the rail should be replaced. Typically a
bowing displacement of about 0.2mm will not affect
cutting accuracy.
B.
If the straight edge touches both edges of the
blade initially, but shifts apart as the table travels
along the rail, proceed to method 2 below.
