• Kickback is a sudden reaction to a pinched,
bound or misaligned saw blade, causing
an uncontrolled saw to lift up and out of
the workpiece toward the operator;
• When the blade is pinched or bound
tightly by the kerf closing down, the blade
stalls and the motor reaction drives the
unit rapidly back toward the operator;
• If the blade becomes twisted or misaligned
in the cut, the teeth at the back edge of the
blade can dig into the top surface of the
wood causing the blade to climb out of the
kerf and jump back toward the operator.
Kickback is the result of saw misuse and/
or incorrect operating procedures or
conditions and can be avoided by taking
proper precautions as given below:

maximum speed marked on the tool.
20. Maintain labels and nameplates on the tool.
These carry important safety information.
If unreadable or missing, contact
FB;6PQ RS6=BPTRU VBTUP6UBUW6F6P?S
Harbor Freight Tools for a replacement.
21. Avoid unintentional starting.
Prepare to begin work before turning on the tool.
22. Do not lay the tool down until it has come to
a complete stop. Moving parts can grab the
surface and pull the tool out of your control.
23. When using a handheld power tool,
maintain a firm grip on the tool with both
hands to resist starting torque.
24. Do not depress the spindle lock when
starting or during operation.
25. Do not leave the tool unattended when the
Battery Pack is connected. Turn off the tool,
and remove the Battery Pack before leaving.
26. The battery Charger gets hot during
use. The Charger’s heat can build up to
unsafe levels and create a fire hazard if
it does not receive adequate ventilation,
due to an electrical fault, or if it is used in a
hot environment.

This tool vibrates during use.
Repeated or long-term exposure to vibration may
cause temporary or permanent physical injury,
particularly to the hands, arms and shoulders.
To reduce the risk of vibration-related injury:
1. Anyone using vibrating tools regularly or for
an extended period should first be examined
by a doctor and then have regular medical
check-ups to ensure medical problems are not
being caused or worsened from use. Pregnant
women or people who have impaired blood
Page 6 ;&(%$*4.8"4,7%H'*#$"&8#>%/7*,#*%4,77%IJKKKJKLLJMNON1 Item 57504
circulation to the hand, past hand injuries,
nervous system disorders, diabetes, or
Raynaud’s Disease should not use this tool.
If you feel any symptoms related to vibration (such
as tingling, numbness, and white or blue fingers),
seek medical advice as soon as possible.
2. Do not smoke during use. Nicotine reduces
the blood supply to the hands and fingers,
increasing the risk of vibration-related injury.
3. Wear suitable gloves to reduce the
vibration effects on the user.
Page 7
4. Use tools with the lowest vibration
when there is a choice.
5. Include vibration-free periods each day of work.
6. Grip tool as lightly as possible (while still keeping
safe control of it). Let the tool do the work.
7. To reduce vibration, maintain the tool as

1. Workpiece selection:
a. Workpiece must be free of foreign
objects and loose knots.
b. Do not use to cut logs, tree limbs,
or uneven lumber.
c. Wet lumber, green (unseasoned) lumber,
and pressure treated lumber all have an
increased potential for kickback and should
only be cut with a blade designed for cutting
that lumber. Wear a NIOSH-approved
respirator and have appropriate ventilation
whenever cutting pressure treated lumber.
U&$*- The ruler on the fence shows
the approximate width of cut.
2. If needed, remove the Fence entirely. Otherwise,
tighten the Fence Lock Knob after adjustment.

2. Designate a work area that is clean and well lit.
The work area must not allow access by children
or pets to prevent distraction and injury.
3. Secure loose workpieces using a vise or clamps
(not included) to prevent movement while working.
4. There must not be objects, such as utility lines,
nearby that will present a hazard while working.
This is especially critical for plunge cuts.
