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.
Do not cut badly warped wood. The workpiece must sit flat on the
table without rocking.
Dust created by manufacturing activities may be harmful to
your health.
Your risks from exposure may vary. Always work in a well-ventilated
area and wear safety approved, protective dust masks specifically
designed to filter out microscopic particles. Utilize wood dust
collection systems appropriate to your machine type.
Stand to the right of the workpiece when feeding it through the saw
to avoid potential injury from kickback and loose chips.
To cut a workpiece, perform the following steps:
Step 1: Turn on power to the machine.
Step 2: Make sure the dust collector is operating. If it is not, turn
on dust collector. Note: when operating the CUT 18 for the first time,
ensure the saw blade is turning in the correct direction and that the
blade is mounted correctly. If not, please change the phasing of the
machine so the saw blade turns in the correct direction. Refer to 5.0.
Step 3: Press Saw Blade ON.
Step 4: Turn on the Guard Air and the Cycle Air.
Step 5: Feed the workpiece through the machine. Always use the
fence to position and guide the workpiece. When cutting a long
workpiece, use an infeed and outfeed conveyor table for support.
Step 6: Press the pneumatic control foot pedal or dual push buttons
one time.
Step 7: Wait for the saw to complete the cutting cycle and remove
the workpiece.

8.0 Maintenance
WaRninG
Before performing any type of maintenance or adjustments, make
certain that the machine is disconnected from its power source and
completely shut off.
WaRninG
Never operate the machine until it has been properly lubricated and
all necessary maintenance work has been completed.
NOTE: After changing a setting, making an adjustment, performing
repair/maintenance work, or troubleshooting, please check that all
applicable safety functions are working properly before performing
another operation.
8.1 Cleaning
Clean and remove sawdust and debris on the machine every day
and in between jobs to maintain accurate cutting.
8.2 Lubrication
Every month, check the lubrication level in the lubrication bowl of the
air regulator unit. If necessary, fill the bowl up to 80% of capacity to
ensure that the air cylinder is properly lubricated. Before adding oil,
turn the guard air switch and the cycle air switch to the off position.
Use No. 32 light oil for the lubrication bowl.
Every week, check for accumulated water in the filter bowl of the air
regulator unit. To release water, turn the Guard Air switch to the
off position.

V-belt
5. After V-belt tension is adjusted, tighten the 4 lock screws on the
table to secure the motor in place.
Note: Ensure motor pulley and arbor pulley are square to
prevent vibration.
6. If the back fence position was moved to access the top motor
bolts, re-square the back fence to the saw blade.
Note: After belts have stretched and are re-tensioned, belt life
span will be diminished. Do not replace 1 belt at a time. All 3
should be changed together to maintain equal pressure.
8.5 Replace V-Belts
Replace V-belts if the saw arbor speed decreases or makes an
abnormal sound when starting the saw blade. Replace all three belts
at the same time to ensure a consistent tension on each belt.
To replace V-belts:
1. Disconnect the machine from its power source.
2. Slightly loosen the 4 lock screws on the machine table.
3. Open the front access door, using the supplied door handle.
4. Move the motor towards the arbor until the belts can be
mounted on the pulleys.
5. Once belts are mounted, adjust belt tension (see section 8.4,
steps 4-6).
The V-belt specification is MF-1330. Stiles Part Number:
73-185-50000.
Note: It is recommended to change all 3 belts at the same
time to avoid affecting accuracy of the parallel between the
motor pulley and the spindle pulley. If they are not parallel,
belts will wear very quickly.
