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.
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. Place a straight edge on the cutting table as shown in
Figure 7
.
2. Loosen the left guide rail by untightening the fasteners
found at the ends of the rail. (see figure 7) Do not loosen
the rail too much to avoid excessive play during
adjustments.
3. Make sure the straight edge is placed flush against the
ruler guide. Adjust the left guide rail so 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.
4. Position the table as close to the user as possible. Place
the straight edge flush against the ruler guide and blade.
While gently holding down the straight edge, move the
table towards the rear of the saw and then back. Apply
just enough force to prevent the straight edge from
moving due to table vibrations, but not enough to prevent
the blade from displacing the straight edge. 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 3 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 left rail may be
deformed (i.e. bowed).
See Figure 8.
Typically a
bowing displacement of up to 0.2mm will not affect
cutting accuracy. Perform test cuts to determine if
the rail should be replaced. If a replacement is
required try swapping the left rail with the right rail
and perform the alignment procedure again. If this
does not solve the problem, then replacement rails
will have to be acquired.
B. If the straight edge touches both edges of the blade
intially, but shifts apart as the table travels along
the rail, proceed to method 2 below.
5. Tighten the fasteners at both ends of the left rail. If
alignment has been achieved do not proceed to
method 2.
Method 2:
This procedure corrects another source of misalignment
that occurs when the table’s orientation is not parallel with
the guide rails.
1. Lower the table bracket by loosening the two affixed
bolts. (see figure 9) Remove the table from the rails.
2. If the table shifts to the right as it travels away from the
user, a shim needs to be added to the guide roller furthest
