GENERAL POWER TOOL SAFETY WARNINGS
Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
Work Area safety
1. Keep your work area clean and well lit. Cluttered or dark areas invite accidents.
2. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which ignite
the dust or fumes.
3. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
Electrical Safety
1. Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified
plugs and matching outlets will reduce risk of electric shock.
2. 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
earthed or grounded.
3. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
4. 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 or entangled cords increase the risk of electric shock.
(continued on next page)
WARNING

222
Electrical Safety (Continued)
5. When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
6. If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.
Personal Safety
1. Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use power tool while you are tired or under the influence of
drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury.
2. Use personal protective equipment. Always wear eye protection. Protective equipment such as dust masks, non-skid safety shoes, hard hat, or hearing protection
used for appropriate conditions will reduce personal injury.
3. Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
4. Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
5. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
6. 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.
7. If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can
reduce dust-related hazards.
Power Tool Use and Care
1. Do not force the power tool. Use the correct power tool for your application. The correct tool will do the job better and safer at the rate for which it was designed.
2. Do not use the power tool if switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
3. Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing
power tool. Such preventative safety measures reduce the risk of starting the power tool accidentally.
4. Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool.
Power tools are dangerous in the hands of untrained users.
5. Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool's
operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
6. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
7. Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be per
formed. Use of the power tool for operations different from those intended could result in a hazardous situation.
Service
1. 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.
SPECIFIC SAFETY RULES
1. Hold power tools 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.
2. Use a vise or clamping device to restrain work piece.
(See Definitions for label symbols on pg. 3)
TOOL DESCRIPTION
Dynafile II – Is a electric hand tool with a moving narrow belt. Tool is equipped as shown on page 3.
ASSEMBLY and OPERATION INSTRUCTIONS
1. With power source disconnected from tool rotate head to desired position and tighten set screw with hex wrench provided to clamp.
2. Connect power source to tool. Be careful not to depress switch in the process.
3. Hold tool by the motor housing only. One or two hands may be used. Do Not hold tool by head/housing assembly. Keep hands away from all grinding/sanding edges
and moving parts. A side handle is included for two hand operation of tool.
4. Depress switch to start tool. Switch can be locked with button on side of handle, depress switch to release.
5. Adjust belt tracking by turning 95218 Adjustment Knob to the left or right accordingly, so as abrasive belt rides evenly over contact arm.
6. Working off the return path of the abrasive belt will ensure superior tracking.
MAINTENANCE and ACCESSORY CARE INSTRUCTIONS
Important: A preventative maintenance program is recommended whenever portable power tools are used.
• Use only genuine Dynabrade replacement parts to insure quality. To order replacement parts, specify Model #, Serial # and RPM of your tool.
Routine Preventative Maintenance:
• Mineral spirits are recommended when cleaning the sanding heads. Do not use on electrical components or clean tool or parts with any
solvents or oils containing acids, esters, ketones, chlorinated hydrocarbons or nitro carbons. Compressed air may be used to remove dirt
from electrical components.
• DO NOT clean or maintain tools with chemicals that have a low flash point (example: WD-40®).
• Tool labels must be kept legible at all times, if not, reorder label(s) and replace. User is responsible for maintaining specification
information i.e.: Model #, S/N, and RPM. (See Assembly Breakdown)
• Visually inspect plugs and cords for frays, visible damage and signs of deterioration. Damaged or worn components must be replaced by
Dynabrade to avoid a safety hazard.
• Brush Changing – Unplug tool, remove rear housing and brushes. Install new brushes, and replace rear housing. Run tool for 20 minutes
at free speed to seat brushes. Change brushes every 100 hrs. to ensure proper tool function. After changing brushes it is recommended to
replace the right angle gear grease with 95544 Grease.
• After maintenance is performed on tool check for excessive tool vibration.
• Check for excessive current leakage at 550 volts with a current leakage checker on all screws and the gear case, if the electrical components have been
disturbed during repair.
Handling and Storage of Tool and Accessories:
• Use of tool rests, hangers and/or balancers is recommended.
• DO NOT carry tool by cord.
• Protect abrasive accessories from exposure to water, solvents, high humidity, freezing temperature and extreme temperature changes.
• Store accessories in protective racks or compartments to prevent damage.
Maintenance Instruction
Use compressed air to routinely
blow off vents located at the rear
of the housing.
Compressed air
pressure must not exceed 30
PSIG Maximum.
