WARNING

Do not attempt to operate machine if you are not completely familiar
with its operation. Obtain immediate advice from a supervisor,
instructor, or other qualified personnel.

Use of this machine requires that you give your work your undivided
attention, and careless acts or not paying close attention to work
being performed may result in serious injury to yourself and/or
others. Never operate this or any machine under the influence of
drugs, alcohol, or any medication that may impair judgment.

collection systems appropriate to your machine type.

Avoid Kickback

It is very important that each workpiece be carefully inspected
for stock condition and grain orientation before running through
the machine. Kickback can result when the workpiece has knots,
holes, or foreign materials such as nails. It can also occur when the
material is fed against the grain.

7.2 Machine Operation

Step 1: Adjust Pressure Roller Assembly Height

WARNING

Pressure rollers must be adjusted to the proper position to prevent
kickback.

There are 4 pressure rollers on each side of the saw blade to hold
down the workpiece during the cut. Adjust the height of the pressure
roller assembly according to workpiece thickness.

An adjustment example is shown above.

1. Release the pressure roller locking lever.

2. Pressure roller height is indicated on the scale on the front of
the pressure roller assembly housing. The thickness of the
workpiece should be set using the indicator scale. The pressure
rollers are 2mm lower than the indicator scale to ensure the
correct amount of pressure is applied to the workpiece. When
cutting a thicker workpiece, the indicator scale can be adjusted
2-4mm less than the workpiece thickness to increase pressure.

3. Tighten the pressure roller locking lever to secure the pressure
rollers before running the saw.

1. Loosen screws A, B, and C.

2. Loosen lock nut B2, and turn B3 to the right.

3. Loosen lock nut A2, and turn A3 to the right.

4. Check for squareness.

5. Tighten the lock nuts and securing screws to fix the rip fence in
the correct position.

Step 3: Check Anti-Kickback Fingers

There are three rows of auto-adjust anti-kickback fingers. The anti­kickback fingers do not need to be adjusted.

For safety, be sure the top anti-kickback fingers hang down in a row,
point in the direction of the feed chain, and can be lifted smoothly.
Be sure the bottom anti-kickback fingers press down and lift up
smoothly.

Step 4: Start the Saw Blade

WARNING

The optimal feed speed varies depending on the material being cut
and the cut quality desired.

Increase speed by turning clockwise; decrease by turning
counterclockwise.

Always wear leather gloves, a leather apron, and a face shield.

Step 6: Activate the Laser Cutline Guide

To ensure cutting accuracy the entire length of the workpiece, use
the laser cutline guide.

To activate, plug in the laser on the right side of anti-kickback finger
support arm.

The laser should accurately indicate the cut line path. If the laser line
does not align with the cut line, use the adjustment screws located
on the laser bracket to align.

ADJUSTMENT TIP: Mark the laser line on the board before cutting
for reference after the board is cut.

Step 7: Make Your Cut

WARNING

If you are inexperienced at rip sawing, become familiar with the
machine and its operation before doing normal work. Use scrap
pieces of lumber that are not warped, bowed, or too small.

Stand to the side of the workpiece when feeding it through the saw
to avoid potential injury from kickback and loose chips.

Keep your hands away from the saw blade area.

To stop a workpiece before it is entirely fed through the machine,
press OFF. Wait until the saw blade has completely stopped before
removing material. Attempted removal while saw blade is turning
may cause kickback.

The four sides of the workpiece should be even in thickness to
obtain a precise straight-line rip, Thickness should not exceed
4" (400mm). The workpiece should not be curved, warped, or
deformed.

The workpiece should be at least 10" (250mm) long to ensure the
pressure rollers hold the workpiece properly for a high-quality cut.

Stand at the side of the machine. Never stand behind the ripping
line. The danger zone includes an angle of 30 degrees on both sides
of the ripping line.

Place the workpiece on the worktable against the fence and feed it
between the feed chain and pressure rollers to begin sawing.

WARNING

The operator MUST let go of the workpiece as soon as it has been
pushed into the machine. If the workpiece does not enter into the
machine properly, the operator should NEVER attempt to straighten
it with his/her hands.

After the cut, check the profiles of the workpiece to verify that the
cut quality is acceptable and that the feed speed is correct. Adjust
the feed speed if necessary (see Step 5).

WARNING

Never leave the machine unattended while in use. After switching
off the machine, be certain to wait until the saw blade comes to a
complete stop before walking away.

7.3 Rip Sawing Tips

When the edges of a workpiece are not square, the wider side
should always face down on the feed chain. The wider portion
will maintain more surface area on the feed chain for maximum
accuracy.

face down on the feed chain. If the convex side faces up, the saw
blade might become clamped by the workpiece, causing kickback.

When a workpiece is warped lengthwise, the convex side should
face up on the feed chain. If the convex side faces down, the
pressure rollers will not work smoothly, which can affect accuracy.

7.4 Adjust Oil Supply to Feed Chain

The central lubrication system automatically applies oil at specific
intervals. The intervals can be adjusted according to conditions.
If the oil in the tank is below the minimum allowed value, the feed
chain will stop running automatically to prevent damage.

Oil flows from the central lubrication system to the oil distributor,
which then distributes oil to various points. The image below shows
the lubrication points and which line lubricates which point.

Check every day before machine operation to ensure the oil reservoir
is full.

Before starting the machine, press the manual lubrication button
located on the front of the lubricator for 10-15 seconds to start the
flow of oil to the lubrication points. When starting the machine, make
sure the lubricator is in the intermittent OFF position to avoid over
lubrication due to repetitive starting.

NOTE: The oil pump in the central lubrication device is not intended
for continuous pumping for an extended time. Pressing the manual
lubrication button for more than 3 minutes may damage the oil
pump motor.
