Head Assembly Lock Pin
The head assembly lock pin (item 43 - page 12)
is located on the right side of the pivot post
(item 34 -page 12). It is used to hold the saw's
head assembly in the DOWN position. This po-
sition prevents the head from bouncing up and
down during transportation. This also makes
the saw more compact for lifting and storage.
This position is also required for some calibrat-
ing procedures.
To Engage the Head Assembly
1. Check that the depth stop plate (item 33 -
page 12) is disengaged, or pressed in to the
left position.
2. Grasp the saw's main handle (item 3 - page
11) and press down on the head assembly.
3. While pressing the saw head down, push in
on the head assembly lock pin. Release the
head assembly. The head will be locked in
the DOWN position (see Fig. 11).
To Adjust the Glide Movement
Controller
The glide movement controller is attached to
the upper joint of the glide mechanism; it is de-
signed to control the smoothness of the saw's
glide action. When assembled at the factory,
the controller is not adjusted; therefore, the
movement is very smooth. To adjust the glide
mechanism's smoothness, slightly tighten or
loosen the two screws at the top by using the
6/4mm hex key or a 4mm hex key (see Fig. 12).
