WORK AREA SAFETY
• Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.
•
Do not operate power tools in explosive atmospheres, such as in the presence of
flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.
•
Keep bystanders, children, and visitors away while operating a power tool.
Distractions can cause you to lose control.
ELECTRICAL SAFETY
• Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any
adaptor plugs in any earthed (grounded) power tools. Double insulated tools are equipped with a polarized
plug (one blade is wider than the other). This plug will fit in a polarized outlet only one way. If the plug does not
fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install a polarized
outlet. Do not change the plug in any way. Double insulation eliminates the need for the three wire grounded
power cord and grounded power supply system.
•
Do not expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
•
Avoid body contact with earthed or grounded surfaces such as pipes,
radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is
grounded.
•
Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep
cord away from heat, oil, sharp edges or moving parts. Damaged cords increase the risk of electric shock.
•
When operating a power tool outside, use an extension cord suitable for
outdoor use. These cords are rated for outdoor use and reduce the risk of electric shock.
•
Do not use AC only rated tools with a DC power supply. While the tool may appear to
work. The electrical components of the AC rated tool are likely to fail and rate a hazard to the operator.
PERSONAL SAFETY
• 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.
•
Use safety equipment. Always wear eye protection. Safety equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection for appropriate conditions will reduce personal injuries.
•
Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from
moving parts. Loose clothes, jewelry or long hair can be caught in moving parts. Air vents may cover moving
parts and should be avoided.
•
Avoid accidental starting. ensure the switch is in the off position before plugging in. Carrying power
tool with your finger on the switch or plugging in power tools that have the switch on invites accidents.
•
Remove any adjusting keys or wrenches before turning the power tool on. A
wrench or key that is left attached to a rotating part of the tool may result in personal injury.
•
Do not overreach. Maintain proper footing and balance at all times. Loss of balance can cause an injury
in an unexpected situation.
•
If devices are provided for connection of dust extraction and collection
facilities, ensure these are connected and properly used. use of these devices can
reduce dust related hazards.
•
Do not use a ladder or unstable support. Stable footing on a solid surface enables better
control of the tool in unexpected situations.
•
Keep tool handles dry, clean and free from oil and grease. Slippery handles cannot
safely control the tool.
TOOL USE AND CARE
• Secure the workpiece. use clamp or other practical way to hold the workpiece to a stable platform.
Holding the workpiece by hand or against your body is unstable and may lead to loss of control.

manufacturer or intended for use on this type tool may cause damage to the tool or result in personal injury to
the user. Consult the operator’s manual for recommended accessories.
•
Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
•
Feed the workpiece in the correct direction and speed. Feed the workpiece into a
blade, cutter, or abrasive surface against the direction of the cutting tool’s direction of rotation only. Incorrectly
feeding the workpiece in the same direction may cause the workpiece to be thrown out at high speed.
•
Never leave the tool running unattended, turn the power off. Do not leave the tool
until it comes to a complete stop.
WARNING: USE OF THIS TOOL CAN GENERATE AND DISBURSE DUST OR
OTHER AIRBORNE PARTICLES, INCLUDING WOOD DUST, CRYSTALLINE SILICA DUST
AND ASBESTOS. Direct particles away from face and body. Always operate tool in a well-
ventilated area and provide for proper dust removal. Use dust collection system wherever
possible. Exposure to the dust may cause serious and permanent respiratory or other
injury, including silicosis (a serious lung disease), cancer, and death. Avoid breathing the
dust, and avoid prolonged contact with the dust. Allowing dust to get into your mouth or
eyes, or lay on your skin may promote absorption of harmful material. Always use properly
fitting NIOSH/OSHA approved respiratory protection appropriate for dust exposure, and
wash exposed areas with soap and water.
SERVICE
• Have your power tool serviced by a qualified repair person using
only identical
replacement parts. This will ensure that the safety of the power tool is maintained.
•

EXTENSION CORDS
Grounded tools require a three wire extension cord. Double insulated tools can use
either a two or three wire extension cord. As the distance from the power supply outlet increases, you must use a
heavier gauge extension cord. using extension cords with inadequately sized wire causes a serious drop in voltage,
resulting in loss of power and possible tool damage. Refer to the table shown below to determine the required
minimum wire size.
The smaller the gauge number of the wire, the greater the capacity of the cord. For example: a 14-gauge cord
can carry a higher current than a 16-gauge cord. When using more than one extension cord to make up the total
length, be sure each cord contains at least the minimum wire size required. If you are using one extension cord for
more than one tool, add the nameplate amperes and use the sum to determine the required minimum wire size.
Guidelines for Using Extension Cords
• If you are using an extension cord outdoors, be sure it is marked with the suffix “W-A” (“W” in Canada) to
indicate that it is acceptable for outdoor use.
• Be sure your extension cord is properly wired and in good electrical condition. Always replace a damaged
extension cord or have it repaired by a qualified person before using it.
• Protect your extension cords from sharp objects, excessive heat, and damp or wet areas.

Reference Guide" Sheet enclosed for details.
This multi-purpose oscillating tool is intended for cutting and sanding wood, plastic, plaster and non-ferrous metals.
It is especially suitable for cutting in tight spaces and for flush cutting
. Following are a few typical uses.
CUTTING (FIG 5,6,7)
use a flush cutting saw blade (or “e-cut blade”) for making precise
cuts in tight areas, close to edges, plunge or flush to a surface.
It is important not to force the tool during the flush cutting. If you
are experiencing a strong vibration in your hand during the cut, it
indicates too much pressure on the tool. Back off on the pressure
and let the speed of tool do the work. See FiG 5, 6 for typical uses
for flush cutting saw blade.

NOTE: It is suggested that you have a piece of
scrap material supporting the blade when making a
flush cut. If you need to rest the blade on a delicate
surface, you need to use cardboard or masking tape
to protect the surface.
use the segmented saw blade for making continuous precise cuts
in wood, plaster or drywall material. Applications include cutting
openings for electrical boxes, repairing flooring, cutting flooring for
venting, and more. See FIG 7 for how to use of the segmented
saw blade.
SANDING (FIG 8)
With sanding accessories, this tool is a detail sander. It is suitable
for dry sanding of wood, plastic, and metal surfaces, especially in
corners, edges and hard to reach areas. See FIG 8.
Tips:
1. Work with the complete surface of the sandpaper, not only with
the tip.
2. Sand with continuous motion and light pressure. Do not apply
excessive pressure. Let tool do the work.
3. Always secure small work pieces.
4. Select suitable abrasive paper for best results.
SCRAPING (FIG 9)
Scraper blades are suitable for removing vinyl, varnish, paint layers,
carpeting, caulk and other adhesives.
use a rigid scraper blade to remove harder materials, such as vinyl
flooring, carpeting and tile adhesives in a large area.
use a flexible scraper blade (not included) to remove softer material
such as caulk.
Tips:
1. When removing strong, tacky adhesive, grease the scraper
blade surface to reduce gumming up.
2. Begin with light pressure. The oscillating motion of accessory
only occurs when pressure is applied to the material to be
removed.
3. If you are removing caulk from a delicate surface, such as a
bath tub or tile back splash, we recommend taping to protect
the surface that the blade will rest on.
GROUT REMOVAL (FIG 10)
use a grout removal blade (not included) to remove damaged or
cracked grout, or in order to replace a damaged or broken tile.
To remove the grout, use a back and forth motion, making several
passes along the grout line. Be careful not to apply too much side
pressure on the grout blade. See FIG 10.
