`Loosen the belt tension by turning of the screw
4 counterclockwise and moving the upper drive
wheel down to the stop or tapping on the screw
by hand down to the stop;
`remove the blade from the upper and lower
wheels and pull it out through the slot of the
table;
ATTENTION!
To avoid injury and damages STRONGLY
recommend that you contact with saw blade
wearing in gloves.
`install a new blade in reverse order so that the
blade teeth are downward. Adjust the position of
the blade strictly on the center of wheels;
Note! New blade is unstretched and may not be
put on wheels. For ease of installation put a blade
on the lower wheel, pull it, as far as possible, on
the upper wheel and, by turning of the wheel, get
full installation of the blade. This method is also
convenient to adjust a centering of blade.
`by rotating of the screw 4 clockwise, do the blade
tension according to the section Getting Started.
Check and, if necessary, adjust an alignment of the
planes of upper and lower wheels:
`turn the upper wheel clockwise for several turns
and check a disalignment of blade from the center
of the wheel;
`if the blade dislocated to the front of the
machine, you should get an unavailability
of disalignment by rotation of the screw 12
clockwise. Here again adjust the position of the
blade in the center;
`if the blade dislocated to the rear of the machine,
an adjustment should be performed by rotating
the screw 12 counterclockwise;
`check the position of the blade on the lower
wheel. If necessary, adjust the position of the
blade by the center of the wheel;
`by the rotation of the upper wheel for some turns,
be sure in an unavailability of disalignment
from the center position. If necessary, repeat the
adjustment;
`close the machine cover and tighten the screws 6.
A list of the respective blades can be found on page
12.
To avoid vibrations of the saw blade and poor
cutting results during working operation, adjust
the limiters (upper limiter 5 and bottom limiter):
Note! Adjust the limiters after the blade tension
only. Adjustment is described on the example
of ZPL-305. For ZPL-350-190 all operations are
similar.
а) Adjustment of the upper limiter:

`provide a safety detent of a blade by a bearing
27 in avoid of its disalignment under pressure of
the workpiece. To do this, rotate the adjusting
screw 26 and adjust the clearance between
the bearing and the rear edge of the blade is
equal to 0.7-1mm. Tighten the locking screw;
Note! To prevent premature run-out of the bearing,
the bearing must not be pressed against the blade.
`provide a limit of blade vibrations by releasing (use
a hex key) of xing screws 25 and adjusting the
position of the pins 24 in the vicinity of the blade
(without its touching). Tighten the screws;
`закройте крышку изделия и заверните винты 6.
b) Adjustment of the lower limiter:
`loosen the xing screws 6 of the cover and open
it. Limiter is under work table;
`provide a safety detent of a blade by a bearing
in avoid of its disalignment under pressure of the
workpiece. To do this, loosen the locking screw
29 and adjust the clearance between the bearing
and the blade is equal to 0.7-1mm. Tighten the
locking screw;
`the setting of the lower limiter’s pins is similar
as for upper pins.
Getting Started
Check the tension of the blade. The properly
tensioned blade should NOT slip on the drive
wheels. If necessary, you can increase the tension
of the blade by rotating of the screw 4 clockwise.
Based on the workpiece and the nature of the
work:
а) Adjust the position of the upper limiter 5:
`loosen the screw of the regulator 10;
`adjust the position of the lowest point of the
limiter at a height of 2-3 sm from the top of
the workpiece by rotating of the fly screw (for
ZPL-305) or manually (for ZPL-350-190),
depending on the thickness of the workpiece;
`tighten the screw of the regulator 10.
b) Adjust the position of the longitudinal
guide 3:
`lift the locking handle 19 of the guide;
`set the edge of guide according to the saw off width
of the workpiece;
`lock the guide.
Note! To avoid uneven cutting, as well as damage
(due to bending and twisting) of the saw blade,
always use the longitudinal guide when cutting.
c) If necessary an oblique cutting of workpiece, set
the angle detent at the desired angle.
d) If necessary to cut the workpiece with any angle
up to 45°, to set the angle of the table:
`loosen the xing of table tilt by the handle 11;
`set the desired angle of cutting with a tilt pointer
of the table bracket 8;
`lock the table tilt by the handle 11.
e) Check the tension of the driving belt 22 (only
for ZPL-305). Well tensioned belt means that
when you press on it at the center between the
pulleys, the deflection should not exceed 1sm.
Otherwise, adjust the belt tension by the rotation
of the handle 30.
f) Check (only for ZPL-305) an adjusted speed of
blade. It should match to the workpiece material
and to the upcoming kind of the work. To do this:
`remove the fastening screws 6 of the lower
cover and open the cover;
`check the position of the belt 22 on the pulleys
and determine the current speed:
– the belt on a front pair of pulleys - higher
speed of movement of the blade;
– the belt on a rear pair of pulleys - lower speed
of movement of the blade.
If necessary, you can set the speed that you need:

`remove the belt and install it on the other pair
of pulleys;
`tighten the belt in accordance with Section
ASSEMBLY, by rotation of the handle 30 in the
opposite direction;
`close the product cover and tighten the screws 6.
To reduce the amount of dust when working, we
recommend to connect a vacuum cleaner (not
included) to the dust-removing socket 14. Socket
diameter is 40 mm (for ZPL-305 - 40/70 mm). You
may need an adapter (not included).
Prepare for your work:
`make sure that the saw blade is on the wheels,
correctly installed and strained;
`remove all keys and not necessary objects away
from the rotating parts of the machine and from the
working area;
`make sure that the workpiece has no metal
objects (nails, screws and so on).
Operating procedure
Connect the product to the power.
ATTENTION!
The machine complies with the level I of
protection against electric shock, i.e. it must be
