GENERAL POWER TOOL SAFETY WARNINGS

WARNING
Read all safety warnings, instructions, illustrations and specifi cations provided with this power tool.
Failure to follow all instructions listed below may result in electric shock, fi re 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.

1) Work area safety
a) Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
b) 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.
c) Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.

2) Electrical safety
a) 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.
b) 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.
c) Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric shock.
d) 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.
e) 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.
f) 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.

3) Personal safety
a) Stay alert, watch what you are doing and use common sense when operating a power tool.
Do not use a power tool while you are tired or under the infl uence of drugs, alcohol or medication.
A moment of inattention while operating power tools may result in serious personal injury.
b) Use personal protective equipment. Always wear eye protection.
Protective equipment such as a dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personal injuries.
c) 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 fi nger on the switch or energising power tools that have the switch on invites accidents.
d) 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.
e) Do not overreach. Keep proper footing and balance at all times.
This enables better control of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing away from moving parts.
Loose clothes, jewellery or long hair can be caught in moving parts.
g) 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.
h) Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles.
A careless action can cause severe injury within a fraction of a second.

4) Power tool use and care
a) Do not force the power tool. Use the correct power tool for your application.
The correct power tool will do the job better and safer at the rate for which it was designed.
b) Do not use the power tool if the switch does not turn it on and off .
Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
c) D isconnect the plug from the power source and/or remove the battery pack, if detachable, from the power tool before making any adjustments, changing accessories, or storing power tools.
Such preventive safety measures reduce the risk of starting the power tool accidentally.
d) 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.
e) Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may aff ect the power toolʼs operation.
If damaged, have the power tool repaired before use.
Many accidents are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
g) 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 performed.
Use of the power tool for operations diff erent from those intended could result in a hazardous situation.
h) Keep handles and grasping surfaces dry, clean and free from oil and grease.
Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

5) Service
a) Have your power tool serviced by a qualifi ed repair person using only identical replacement parts.
This will ensure that the safety of the power tool is maintained.

CAUTION
Keep children and infi rm persons away.
When not in use, tools should be stored out of reach of children and infirm persons.

PLANER SAFETY WARNINGS

1. Wait for the cutter to stop before settling the tool down.
   An exposed rotating cutter may engage the surface leading to possible loss of control and serious injury.

2. Hold the power tool by insulated gripping surfaces, because the cutter may contact its own cord. Cutting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.

3. Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the workpiece by your hand or against the body leaves it unstable and may lead to loss of control.

ADDITIONAL SAFETY WARNINGS

1. Do not use the Planer with the blades facing upward (as stationary type planer).

SPECIFICATIONS

STANDARD ACCESSORIES

In addition to the main unit (1 unit), the package contains the accessories listed in the below.

OPTIONAL ACCESSORIES

(sold separately)

1. Elbow
2. Dust bag

APPLICATIONS

Planing various wooden planks and panels. (See Fig. 1-4)

PRIOR TO OPERATION

1. Power source
   Ensure that the power source to be utilized conforms to the power requirements specifi ed on the product nameplate.

2. Power switch
   Ensure that the power switch is in the OFF position. If the plug is connected to a receptacle while the power switch is in the ON position, the power tool will start operating immediately, which could case a serious accident.

3. Extension cord
   When the work area is removed from the power source. Use an extension cord of suffi cient thickness and rated capacity. The extension cord should be kept as short as practicable.

4. Prepare a stable wooden workbench suitable for planing operation. As a poorly balanced workbench creates a hazard, ensure it is securely positioned on fi rm, level ground.

PLANING PROCEDURES

1. Operation of the switch
   The trigger switch lock-off button is designed to prevent inadvertent operation of the power tool. To operate the power tool, it is necessary to fi rst fully insert the lock-off button into the hole on the handle.
   The trigger switch will not operate unless the lock-off button has been pushed in.
   When the trigger switch is released, the power goes off and the lock-off button automatically returns to its initial position, locking the trigger switch.

2. Adjusting the cutter depth
   
   (1) Turn the knob in the direction indicated by the arrow in Fig. 5 (clockwise), until the triangular mark is aligned with the desired cutting depth on the scale. The scale unit is graduated in millimeters.
   (2) The cutting depth can be adjusted within a range of 0 – 1.5 mm.

3. Surface cutting
   Rough cutting should be accomplished at large cutting depths and at a suitable speed so that shavings are smoothly ejected from the machine. To ensure a smoothly finished surface, finish cutting should be accomplished at small cutting depths and at low feeding speed.

4. Beginning and ending the cutting operation
   
   As shown in Fig. 6 , place the front base of the planer on the material and support the planer horizontally. Turn ON the power switch, and slowly operate the planer toward the leading edge of the material. Firmly depress the front half of the planer at the fi rst stage of cutting, as shown in Fig. 7 , depress the rear half of the planer at the end of the cutting operation. The planer must always be kept flat throughout the entire cutting operation.
   

5. Precaution after finishing the planing operation
   When the planer is suspended with one hand after finishing the planing operation, ensure that the cutting blades (base) of the planer do not contact or come too near your body. Failure to do so could result in serious injury.

   Continued use of dull or damaged blades will result in reduced cutting effi ciency and may cause overloading of the motor. Sharpen or replace the blades as often as necessary.

2. Handling
   CAUTION
   The front base, rear base, and cutting depth control knob are precisely machined to obtain specifi cally high precision. If these parts are roughly handled or subjected to heavy mechanical impact, it may cause deteriorated precision and reduced cutting performance. These parts must be handled with particular care.

3. Inspecting the mounting screws
   Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loose, retighten them immediately. Failure to do so could result in serious hazard.

4. Inspecting the carbon brushes ( Fig. 28 )
   The motor employs carbon brushes which are consumable parts. Since an excessively worn carbon brush can result in motor trouble, replace the carbon brushes with new ones having the same carbon brush No. shown in the fi gure when it becomes worn to or near the “wear limit”. In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.
   

5. Replacing carbon brushes ( Fig. 28 )
   After removing the chip cover, use a slotted screwdriver to disassemble the brush caps.
   The carbon brushes can then be easily removed with the spring.
