Warning:
When using electric tools, basic safety precautions should always be followed to
reduce the risk of a fire, electric shock, and personal injury, including the following:
1. Keep work area clean. Cluttered areas and benches invite accidents.
2. Consider work area environment. Do not expose tools to rain. Keep
work area well lit. Do not use power tools in damp or wet locations.
Do not use tools in the presence of flammable liquids or gases.
3. Guard against electric shock. Prevent body contact with grounded surfaces.
For example; pipes, radiators, ranges, refrigerator enclosures.
4. Keep children away. Do not let visitors contact tool or extension cord.
All visitors should be kept away from work area.
5. Store idle tools. When not in use, tools should be stored in a dry, or locked
place - out of the reach of children.

7. Use the right tool. Do not force a small tool or attachment to do the job of
a heavy duty tool. Do not use tool for purposes not intended.
8. Dress properly. Do not wear loose fitting clothing or jewelry. Clothes can
be caught inmovingparts. Rubbergloves andnon-skidfootwear are
recommended when working outdoors. Wear protective hair covering to
contain long hair.
9. Use safety glasses. Alsouse face-shieldordust maskifoperation areaisdusty.
10. Do not abuse cord. Never carry tool by cord or yank it to disconnect from
receptacle. Keep cord from heat, oil and sharp edges.
11. Secure work. Use clamps or a vice to hold workpiece. It’s safer than using
your hand and it frees up both hands to operate tool.
12. Do not overreach. Keep proper footing and balance at all times.
13. Maintain tools with care. Keep tools clean for better use and safer
performance. Follow instructions for lubricating and changing accessories.
Inspect tool cords periodically and if damaged, have repaired by authorized
service facility. Inspect extension cords periodically and replace if damaged.
Keep handles dry, clean and free from oil and grease.
14. Do not leave tool running. Disconnect tools when not in use, before
servicing, when changing belts, contact arms, etc.
15. Remove keys and wrenches. Form a habit of checking to see that all
keys and adjusting wrenches are removed from tool before turning it on.
16. Avoid accidental starting. Do not carry around plugged in tool with finger
on switch. Be sure switch is off when plugging in.
17. Out-door use extension cords. When tool is used outdoors, use only
extension cord suitable for outdoor use. They should be marked with the
suffix W-A(for UL) or W (for CSA in Canada).
18. Stay alert. Watch what you are doing. Use common sense. Do not operate
tool when you are tired.
19. Check damaged parts. Before further use of the tool, a guard or other part
that is damaged should be carefully checked to determine that it will operate
properly and perform its intended function. Check for alignment of moving
parts, breakage of moving parts, binding of moving parts, mounting and any
other conditions that may affect its operation. Aguard or other part that is
damaged should be properly repaired or replaced by an authorized service
center unless otherwise indicated elsewhere in this instruction manual.
Have defective switches replaced. Do not use tool if switch does not
turn tool on or off.
20. Avoid gaseous areas. Do not operate portable electric tools in
gaseous or explosive atmospheres. Motors in these tools normally
spark, and the sparks can ignite fumes.
21. Do not alter or misuse tool. This tool is precision built. Any
alteration or modification not specified is misuse and may result in a
dangerous condition. Only these accessories and attachments that
are found in this instruction manual are acceptable for use with this
tool. The use ofany otheraccessoryorattachmentmight present a risk
totheoperator.
22. Replacement parts. When servicing, use only identical replacement
parts. When ordering replacement parts, please specify model and
serial numbers of your machine.
Voltage Warning
Before connecting the tool to a power source (receptacle, outlet, etc.),
be sure the voltage supplied is the same as what is specified on the
nameplate of the tool. Apower source with greater than that specified
for tool can result in serious injury to the user as well as damage to
the tool. Using a power source with voltage less than the nameplate
rating is harmful to the tool’s motor. If in doubt, do not plug in the tool.
Insulation
Electric Dynafile® is insulated according to DIN 57740/VDE 0740
and CEE-publication 20. Radio-shielded according to DIN 57875/VDE
0875 and CISPR. To protect the insulation do not drill any hole in
motor housing to fit any labels, use only stickers when it is required, to
give you added safety. Tools built with this type of insulation system are
not intended to be grounded. As a result, your Electric Dynafile® is
equipped with a two prong plug which permits you to use extension cords
without concern for maintaining a ground connection.
Note: Insulation does not take the place of normal safety precautions when
operating this tool. The insulation system is added for protection against
injury resulting from a possible electrical insulation failure within the tool.
Caution: When servicing insulated tools, use only identical replacement
parts. Repair or replace damaged cords.
Extension Cords
Insulated tools have two-wire cords, and can be used with either two-
wire or three-wire extension cords. Only round jacketed extension cords
should be used, and we recommend that they be listed by Underwriters
Laboratories (UL) - (CSAin Canada). If the extension cords will be used
outside, the cord must be suitable for outdoor use. They should be
marked with the suffix W-A(for UL) or W (for CSA in Canada). Any cord
marked as an outdoor cord can also be used for indoor work.
Important: To increase the life of the electrical motor it is absolutely
necessary to clean the inside by blowing carefully compressed air
through the ventilation channels.
Sound Level: 85 - 88 dBA.
Warning: Keep extension away from the immediate working area.

Abrasive Belt/Contact Arm Change Instructions
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
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 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 isacceptable 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 sharp objects, excessive heat and damp or wet areas.
