Never allow a power tool to be used by persons not familiar with correct handling (such as children) or by those who cannot handle the tool correctly.

1. CONFIRM THAT NO ITEMS SUCH AS AN ELECTRIC CABLE OR CONDUIT ARE BURIED INSIDE. In places where live wiring may be hidden behind a wall, floor, ceiling, etc. do not hold or contact any metal parts of the tool. In such cases, metal parts could become electrically live and present a serious shock hazard.

2. KEEP THE RIGHT PARTS IN THE RIGHT POSITIONS.

Do not remove covers and screws which have been factory-mounted. They perform important respective roles. Keep them in the right positions.

1. SHOULD THE PLASTIC HOUSING OR HANDLE OF A POWER TOOL BE CRACKED OR DEFORMED, DO NOT USE IT.

Since cracked or deformed parts may lead to an operator receiving an electric shock, do not use such a power tool. Immediately have it repaired.

1. SECURELY MOUNT ACCESSORIES AND BLADES TO THE TOOL MAIN BODY. Extra care must be taken when using tools on elevated location (such as a roof ladder, scaffold, or the like) to prevent injury to someone on a lower level in the event the tool and/or accessory should drop.

2. ALWAYS KEEP THE MOTOR AIR VENT FULLY OPENED.

A constantly open motor air vent is necessary to allow air to come in and out for cooling the motor. Do not allow it to become clogged up, even if dust is blown through it.

1. OPERATE POWER TOOLS AT THE RATED VOLTAGE.

Operate power tools at voltages specified on their nameplates.

1. NEVER TOUCH THE MOVING PARTS.

Never touch the moving parts such as blades, bits, cutters and others.

1. WHEN REPLACING A COMPONENT PART, ADOPT THE SAME TYPE.

When replacing a component part with a new one, adopt the same type of new part. Also, never attempt to repair a power tool yourself.

SAVE THESE INSTRUCTIONS

SERVICE AND REPAIRS

All quality tools will eventually require servicing or replacement of parts due to wear from normal use. These operations should ONLY be performed by an AUTHORIZED HITACHI POWER TOOL REPAIR SHOP.

REPLACEMENT PARTS

When servicing use only identical replacement parts.

POLARIZED PLUGS

To reduce the risk of electric shock, this equipment has 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 the proper outlet.

Do not change the plug in any way.

DOUBLE INSULATION SYSTEM ENHANCES SAFE OPERATION

To enhance safe operation of this electric power tool, HITACHI has adopted a double insulation system. The term "double insulation" used here denotes an insulation system with two insulations physically separated and arranged between the electrically conductive material

connected to the power supply and the outer frame subject to contact by the operator. Thus, the power tool is termed double insulated and both the “回” mark and “Double insulation”, or either one is indicated on the name plate. While no external grounding is required with this system, normal safety precautions as outlined in this manual must still be followed.

To maintain the effectiveness of the double insulation system, follow the precautions described below:

1. Always contact your dealer or an authorized HITACHI power tool repair shop when assembling, disassembling or replacing parts other than accessories or carbon brushes. Improper assembly and/or replacement with wrong parts may result in eliminating the double insulation-feature.
2. Clean the exterior of the tool with a soft cloth moistened with soapy water, and dry thoroughly. Chloric solvent, gasoline, and thinner will cause plastic components to dissolve.

PRECAUTIONS ON USING BELT SANDER

1. Align the inside arrow mark of the sanding belt with the revolving direction of the drive pulley.
2. Sanding by applying impact and cutting by side-of-belt contact should be avoided.
3. Be careful of sanding sparks.
4. After operation sweep the sanding dust from the dust bag to avoid serious accidents.
5. Don't use water, or oil as lubricant.
6. Ascertain that the sanding workpiece contains neither nails nor other harmful foreign matter.
7. Sanding glass fiber not recommended.

Turn adjust screw clockwise to move belt in.
- Turn adjust screw counterclockwise to move belt out.

Caution: If sanding belt moves during operation, ad- Side justment can be made while in operation.

Fig. 3

2. To turn on switch

Turn on switch while holding machine away from surface to be worked on.

If machine is placed on surface when switch is pushed, surface may be badly scratched.

The same applies when stopping the machine.

3. How to hold machine

Grasp handle and handle knob and hold machine against surface to be worked on so that it contacts surface lightly.

Weight of machine itself is sufficient for sanding and polishing at highest efficiency.

Do not apply any additional pressure, for this would place unnecessary load on motor, shorten life of sanding belt and lower work efficiency.

4. How to move machine

Move machine forward first and then backward, repeating this motion.

5. How to select proper sanding belt

Choose sanding belt of proper grain size and grain type for your specific purpose, by referring to Tables 2 and 3 below.

Table 2.

Derised finish	Proper grain size
Coarse finish	30~40
Medium finish	40~100
Semi fine finish	80~240
Fine finish	180~400

Table 3.

Grain type	Surface to be worked on
AA	Steel, Wood
WA	Wood, Bamboo (8 grain sizes are available # 40, 60, 80, 100, 120, 150, 180 and 240)
CC	Nonferrous metals, slate, plastics, concrete

Cautions :

● For grain sizes, refer to Table 1.
- Sanding belt grain should be coarser than sandpaper used for manual work.
- Use sanding belt of same grain size until uniform surface is obtained.

Changing grain sizes may result in poor finish.

6. How to change belt speed

Either High-speed or low-speed operation can be selected according to the materials or the operating conditions. Selection sanding belt operating speed can be achieved by shifting the tumbler switch in a specified direction.

Caution : Sanding belt installed in the wrong direction will lower work efficiency and shorten life of sanding belt.

(3) Push lever with finger, idle pulley will then move forward and give proper tension to sanding belt.

In this case, be careful not to be hit your finger by lever.

Then, adjust sanding belt position. (refer to page 7)

2. How to remove sanding belt.

Pull lever with finger, sanding belt will then sag and can be taken off pulleys easily.

DUST REMOVAL

When an excessive amount of dust is deposited in the dust bag, dust-collecting efficiency will sharply drop.

Remove dust from the bag when it is deposited up to about 2/3 the bag capacity, where by dust collecting efficiency (as well as working efficiency) will be ensured.

Remove dust from the bag as follows :

(1) Loosen the support bar and remove the dust bag.
(2) The bag inlet can be opened by unzipping the slide fastener.

MAINTENANCE AND INSPECTION

Caution: Be sure to switch power OFF and disconnect the plug during maintenance and inspection.

1. Inspecting the Sanding Belts.

If a loaded and blunt sanding belt is kept in use, efficiency will extremely drop.

Therefore, be sure to sand well the sanding belt in good time.

2. Inspecting tightness of various screws

Periodically inspect each screw tightness of individual components. If any screws are loosened, securely retighten them. Loosened screws, if unheeded, may cause a hazardous situation.

3. Inspecting the carbon brushes

The motor employs carbon brushes as expendable components.

If the brushes are worn, motor trouble may result. When brushes are worn down to the limit line, replace them with new brushes.

Also, keep the carbon brushes clean, so that they can be smoothly slide into the brush holders.
