5. Avoid body contact with grounded sur-
faces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of
electric shock if your body is grounded.
14. Use safety equipment. Always wear eye
protection. Dust mask, non-skid safety
shoes, hard hat, or hearing protection must
be used for appropriate conditions. Ordinary
eye or sun glasses are NOT eye protection.
6. Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
Tool Use and Care
15. Use clamps or other practical way to
secure and support the workpiece to a
stable platform. Holding the work by hand or
against your body is unstable and may lead
to loss of control.
7. Do not abuse the cord. Never use the cord
to carry the tools or pull the plug from an
outlet. Keep cord away from heat, oil,
sharp edges or moving parts. Replace
damaged cords immediately. Damaged
cords increase the risk of electric shock.
16. Do not force tool. Use the correct tool for
your application. The correct tool will do the
job better and safer at the rate for which it is
designed.
8. When operating a power tool outside, use
an outdoor extension cord marked “W-A”
or “W”. These cords are rated for outdoor
use and reduce the risk of electric shock.
17. Do not use tool if switch does not turn it
on or off. Any tool that cannot be controlled
with the switch is dangerous and must be
repaired.
Personal Safety
9. Stay alert, watch what you are doing and
use common sense when operating a
power tool. Do not use tool while tired or
under the influence of drugs, alcohol, or
medication. A moment of inattention while
operating power tools may result in serious
personal injury.
18. Disconnect the plug from the power
source before making any adjustments,
changing accessories, or storing the tool.
Such preventive safety measures reduce the
risk of starting the tool accidentally.
19. Store idle tools out of reach of children
and other untrained persons. Tools are
dangerous in the hands of untrained users.
10. Dress properly. Do not wear loose cloth-
ing or jewelry. Contain long hair. Keep
your hair, clothing, and gloves away from
moving parts. Loose clothes, jewelry, or long
hair can be caught in moving parts.
20. Maintain tools with care. Keep cutting
tools sharp and clean. Properly maintained
tools with sharp cutting edges are less likely
to bind and are easier to control.
11. Avoid accidental starting. Be sure switch
is off before plugging in. Carrying tools with
your finger on the switch or plugging in tools
that have the switch on invites accidents.
21. Check for misalignment or binding of
moving parts, breakage of parts, and any
other condition that may affect the tools
operation. If damaged, have the tool ser-
viced before using. Many accidents are
caused by poorly maintained tools.
12. Remove adjusting keys or wrenches
before turning the tool on. A wrench or a
key that is left attached to a rotating part of
the tool may result in personal injury.
22. Use only accessories that are recom-
mended by the manufacturer for your
model. Accessories that may be suitable for
one tool, may become hazardous when used
on another tool.
13. Do not overreach. Keep proper footing
and balance at all times. Proper footing and
balance enables better control of the tool in
unexpected situations.
3
24. When servicing a tool, use only identical
replacement parts. Follow instructions in
the Maintenance section of this manual.
Use of unauthorized parts or failure to follow
Maintenance instructions may create a risk of
electric shock or injury.
SERVICE
23. Tool service must be performed only by
qualified repair personnel. Service or main-
tenance performed by unqualified personnel
could result in a risk of injury.
USE PROPER EXTENSION CORD: Make sure your extension cord is in good condition.
When using an extension cord, be sure to use one heavy enough to carry the current your
product will draw. An undersized cord will cause a drop in line voltage resulting in loss of
power and overheating. Table 1 shows the correct size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage num-
ber, the heavier the cord.

SPECIFIC SAFETY RULES
USB052-2
DO NOT let comfort or familiarity with product (gained from
repeated use) replace strict adherence to trimmer safety rules. If
you use this tool unsafely or incorrectly, you can suffer serious
personal injury.
1. Hold tool by insulated gripping surfaces
when performing an operation where the
cutting tool may contact hidden wiring or
its own cord. Contact with a “live” wire will
make exposed metal parts of the tool “live”
and shock the operator.
4. Check the bit carefully for cracks or dam-
age before operation. Replace cracked or
damaged bit immediately.
5. Avoid cutting nails. Inspect for and
remove all nails from the workpiece
before operation.
2. Wear hearing protection during extended
6. Hold the tool firmly.
period of operation.
7. Keep hands away from rotating parts.
3. Handle the bits very carefully.
8. Make sure the bit is not contacting the
workpiece before the switch is turned on.
4
9. Before using the tool on an actual work-
piece, let it run for a while. Watch for
vibration or wobbling that could indicate
improperly installed bit.
14. Always lead the power supply cord away
from the tool towards the rear.
15. Do not smear the tool base carelessly with
thinner, gasoline, oil or the like. They may
cause cracks in the tool base.
10. Be careful of the bit rotating direction and
the feed direction.
16. Draw attention to the need to use cutters
of the correct shank diameter and suitable
for the speed of the tool.
11. Do not leave the tool running. Operate the
tool only when hand-held.
12. Always switch off and wait for the bit to
come to a complete stop before removing
the tool from workpiece.
17. Some material contains chemicals which
may be toxic. Take caution to prevent
working dust inhalation and skin contact.
Follow material supplier safety data.
13. Do not touch the bit immediately after
operation; it may be extremely hot and
could burn your skin.

tool forward too slowly may burn and mar the cut. The
proper feed rate will depend on the bit size, the kind of
workpiece and depth of cut. Before beginning the cut on
the actual workpiece, it is advisable to make a sample
cut on a piece of scrap lumber. This will show exactly
how the cut will look as well as enable you to check
dimensions.
•
When using the trimmer shoe, the straight guide or the
trimmer guide, be sure to keep it on the right side in the
feed direction. This will help to keep it flush with the side
of the workpiece.

WARNING
Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to the State of California
to cause cancer, birth defects or other reproductive harm. Some examples
of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this

MAKITA LIMITED ONE YEAR WARRANTY
Warranty Policy
Every Makita tool is thoroughly inspected and tested before leaving the factory. It is warranted to be free of
defects from workmanship and materials for the period of ONE YEAR from the date of original purchase.
Should any trouble develop during this one-year period, return the COMPLETE tool, freight prepaid, to one of
Makita's Factory or Authorized Service Centers. If inspection shows the trouble is caused by defective
workmanship or material, Makita will repair (or at our option, replace) without charge.
This Warranty does not apply where:
• repairs have been made or attempted by others:
• repairs are required because of normal wear and tear:
• the tool has been abused, misused or improperly maintained:
• alterations have been made to the tool.
IN NO EVENT SHALL MAKITA BE LIABLE FOR ANY INDIRECT, INCIDENTAL OR CONSEQUENTIAL
DAMAGES FROM THE SALE OR USE OF THE PRODUCT. THIS DISCLAIMER APPLIES BOTH DURING
AND AFTER THE TERM OF THIS WARRANTY.
MAKITA DISCLAIMS LIABILITY FOR ANY IMPLIED WARRANTIES, INCLUDING IMPLIED WARRANTIES OF
"MERCHANTABILITY" AND "FITNESS FOR A SPECIFIC PURPOSE," AFTER THE ONE-YEAR TERM OF
THIS WARRANTY.
This Warranty gives you specific legal rights, and you may also have other rights which vary form state to state.
Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above
limitation or exclusion may not apply to you. Some states do not allow limitation on how long an implied
warranty lasts, so the above limitation may not apply to you.
