THE DEPTH STOP (Fig. 28)
The downward travel of the Cutting Head
can be set so that the saw blade does not
completely cut through the work-piece. This
facility allows your Pingtek machine to cut
slots in a work-piece.
NOTE: It is advisable that the depth of cut
is checked using a scrap piece of timber to
ensure that the slot cut is correct.
NOTE: By making a cut in the work-piece,
and then repeating the cut but with the
work-piece slightly repositioned to the left or
right, it is possible to perform trenching
cuts.
To use the depth stop:
●Loosen the knurled locking nut.
●Adjust the depth stop screw to limit the
saw blades travel to the required depth.
●Once set to the desired depth, tighten the
knurled locking nut against the retaining
bracket to lock the depth stop screw and
ensure that there is no movement.
●When cutting is complete, return the depth
screw to its normal service position. This
will allow the Cutting Head to be locked in
the down position by the head latching pin.
MAINTENANCE
WARNING: Only attempt any
maintenance or adjustment/cleaning
procedures with the machine disconnected
from the mains power supply.
CHANGING THE BLADE
WARNING: Only use genuine Pingtek
blades or blades specifically recommended
by Pingtek in this machine. The machine
must be disconnected from the power
supply before changing the blade is
attempted.
Note: The operator should wear
protective gloves when handling or
changing the machines blade. Do not wear
gloves when operating the machine.

the left to tighten. The inner blade flange
can be left in its service position, but it must
be checked to ensure that it is clean and
free from any debris etc.
Install the new blade. Make sure the
rotation arrow on the blade matches the
rotation arrow on the upper blade guard
NOTE: The blade teeth should always
point downwards at the front of the saw.
●Install the outer blade flange, washer and
arbor screw. (Fig. 31)
Lock the arbor and tighten the arbor screw
using moderate force, but do not
overtighten.
●Ensure the Hex Key is removed and the
arbor lock has released by rotating the
blade by hand.
THE REPEAT STOP (Fig. 32)
The use of the Repeat Stop can greatly aid
the operator when conducting repetitive
cutting operations. When many pieces of
material all cut to the same length are
required, use of the Repeat Stop can assist
accuracy and efficiency.
