RULES FOR SAFE OPERATION
READ AND SAVE ALL INSTRUCTIONS FOR FUTURE USE. Before use, be sure everyone operating this
equipment reads and understands this manual as well as any labels packaged with or attached to the tool.
1. KNOW YOUR POWER TOOL: Read this manual carefully to learn your equipments applications and
limitations as well as potential hazards associated with this type of equipment.
2. GROUND YOUR TOOL: Unless your tool is double insulated, it should be grounded. See Grounding.
3. AVOID DANGEROUS ENVIRONMENTS: Do not use in rain, damp or wet locations, or in the
presence of explosive atmospheres (gaseous fumes, dust or flammable materials). Remove materials
or debris that may be ignited by sparks.
4. KEEP WORK AREA CLEAN AND WELL LIT: Cluttered, dark work areas invite accidents.
5. DRESS PROPERLY: Do not wear loose clothing.These may be caught in moving parts. When
working outdoors, wear rubber gloves and insulated non-skid footwear. Keep hands and gloves away
from moving parts.
6. USE SAFETY EQUIPMENT: Everyone in the work area should wear safety goggles or glasses
complying with current safety standards. Wear hearing protection during extended use and a dust
mask for dusty operations. Hard hats, face shields, safety shoes, etc. should be worn when specified
or necessary.
7. KEEP BYSTANDERS AWAY: Children and bystanders should be kept at a safe distance from the
work area to avoid distracting the operator and contacting the tool or extension cord. Operator should
be aware of who is around them and their proximity.
8. PROTECT OTHERS IN THE WORK AREA: Provide barriers or shields as needed, to protect others
from debris.
9. USE PROPER ACCESSORIES: Using accessories that are not recommended may be hazardous.
Be sure accessories are properly installed and maintained. Do not delete a guard or other safety
device when installing an accessory or attachment.
10. CHECK FOR DAMAGED PARTS: Inspect guards and other parts before use. Check for
misalignment, binding of moving parts, improper mounting, broken parts and any other conditions that
may affect operation. If abnormal noise or vibration occurs, turn the tool off immediately and have the
problem corrected before further use. Do not use a damaged tool. Tag damaged tools “DO NOT
USE” until repaired. A guard or other damaged parts should be properly repaired or replaced. For all
repairs, insist on only identical National replacement parts.

RULES FOR SAFE OPERATION
GROUNDED TOOLS: TOOLS WITH THREE PRONG PLUGS
Tools marked “Grounding Required” have a three wire cord and three prong grounding plug. The plug
must be connected to a properly grounded outlet. See Figure A. If the tool should electrically malfunction
or break down, grounding provides a low resistance path to carry electricity away from the user, reducing
the risk of electric shock.
The grounding prong in the plug is connected through the green wire inside the cord to the grounding
system in the tool. The green wire in the cord must be the only wire connected to the tool's grounding
system and must never be attached to an electrically “live” terminal.
Your tool must be plugged into an appropriate outlet, properly installed and grounded in accordance with
all codes and ordinances. The plug and outlet should look like those in Figure A.
Figure B illustrates a temporary adapter available for connecting grounded plugs (Figure A) to two prong
outlets. The green rigid ear or lug extending from the adapter must be connected to a permanent ground
such as a properly grounded outlet box or receptacle. Simply remove the center screw from the outlet,
insert the adapter and reattach the screw through the green grounding ear to the outlet. If in doubt of
proper grounding, call a qualified electrician. A temporary adapter should only be used until a properly
grounded outlet can be installed by a qualified electrician. The Canadian Electrical Code prohibits the use
of temporary adapters.

WARNING: Electrical cords can be hazardous. Misuse can result in fire or death by electrical
shock. Read carefully and follow all directions.
WARNING: Improperly connecting the grounding wire can result in the risk of electric shock.
Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. Do
not modify the plug provided with the tool. Never remove the grounding prong from the plug. Do not
use the tool if the cord or plug is damaged. If the plug will not fit the outlet, have a proper outlet
installed by a qualified electrician.

RULES FOR SAFE OPERATION
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 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.
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, make 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.
• Keep away from water. Do not use if wet.
• Inspect thoroughly before each use. DO NOT USE IF DAMAGED.
• Make sure equipment is OFF before connecting cord outlet.
• FULLY INSERT plug into outlet.
• Do not remove, bend or modify any metal prongs or pins of cord.
• Do not use excessive force to make connections.
• Do not connect a three prong plug to a two-hole cord.
• Avoid overheating. Uncoil cord and do not cover it with any material.
• Do not walk on cord.
• Do not drive, drag or place objects over cord.
READ AND SAVE ALL INSTRUCTIONS FOR FUTURE REFERENCE.
WARNING: Electrical cords can be hazardous. Misuse can result in fire or death by electrical
shock. Read carefully and follow all directions.

GENERAL OPERATION
HANDLE ADJUSTMENT
AFTER THE PROPER WHEEL ADJUSTMENT IS ACHIEVED, ADJUST HANDLE BY EITHER A OR B:
A. Removing handle adjustment pins, adjust handle to proper
angle and reinsert handle adjustment pins.
B. Lay machine on side, remove handle adjustment pins, adjust
handle to proper angle and reinsert handle adjustment pins.
No matter what the wheel angle is set at, the handle should be adjusted
to the "belt-line" of the operator or to what the operator is comfortable
with (See Figure A).
- Low setting works best on soft sub floors, plywood, luan,
particleboard and wafer board.
- Higher setting works best on direct glued down carpet, vinyl
or tile on concrete.
NOTE: Adjustment by trail at the beginning of a job will give optimum performance.
