SPECIFICATIONS

Due to our continuing program of research and development, the specifications herein are subject to change without notice.
Specifications and battery cartridge may differ from country to country.
Weight, with battery cartridge, according to EPTA-Procedure 01/2003

Intended use
The tool is intended for sawing wood, plastic and ferrous materials.

SAFETY WARNINGS

Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body leaves it unstable and may lead to loss of control.
Always use safety glasses or goggles. Ordinary eye or sunglasses are NOT safety glasses.
Avoid cutting nails. Inspect workpiece for any nails and remove them before operation.
Do not cut oversize workpieces.
Check for the proper clearance beyond the workpiece before cutting so that the blade will not strike the floor, workbench, etc.
Hold the tool firmly.
Make sure the blade is not contacting the workpiece before the switch is turned on.
Keep hands away from moving parts.
Do not leave the tool running. Operate the tool only when hand-held.
Always switch off and wait for the blade to come to a complete stop before removing the blade from the workpiece.
Do not touch the blade or the workpiece immediately after operation; they may be extremely hot and could burn your skin.
Do not operate the tool at no-load unnecessarily.
Always use the correct dust mask/respirator for the material and application you are working with.
Some material contains chemicals that may be toxic. Take caution to prevent dust inhalation and skin contact. Follow material supplier safety data.

SAVE THESE INSTRUCTIONS.
DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to safety rules for the subject product. MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury.

IMPORTANT SAFETY INSTRUCTIONS

FOR BATTERY CARTRIDGE

Do not expose battery cartridge to water or rain. A battery short can cause a large current flow, overheating, possible burns and even a breakdown.
Do not store the tool and battery cartridge in locations where the temperature may reach or exceed 50°C (122°F).
Do not incinerate the battery cartridge even if it is severely damaged or is completely worn out. The battery cartridge can explode in a fire.
Be careful not to drop or strike battery.
Do not use a damaged battery.

SAVE THESE INSTRUCTIONS.

Tips for maintaining maximum battery life

Charge the battery cartridge before completely discharged. Always stop tool operation and charge the battery cartridge when you notice less tool power.
Never recharge a fully charged battery cartridge. Overcharging shortens the battery service life.
Charge the battery cartridge with room temperature at 10°C – 40°C (50°F – 104°F). Let a hot battery cartridge cool down before charging it.
Charge the battery cartridge once in every six months if you do not use it for a long period of time.

FUNCTIONAL DESCRIPTION

CAUTION

Always be sure that the tool is switched off and the battery cartridge is removed before adjusting or checking function on the tool.

Installing or removing battery cartridge

Always switch off the tool before installing or removing of the battery cartridge.
To remove the battery cartridge, withdraw it from the tool while pressing the buttons on both sides of the cartridge.
To install the battery cartridge, hold it so that the battery cartridge front shape fits to that of the battery installment opening and slip it into place. Always insert it all the way until it locks in place with a little click. If not, it may accidentally fall out of the tool, causing injury to you or someone around you.
Do not use force when installing the battery cartridge. If the cartridge does not slide in easily, it is not being inserted correctly.

Battery protection system
The tool is equipped with a battery protection system. This system automatically cuts off power to the motor to extend battery life. The tool will automatically stop during operation if the tool and/or battery are placed under one of the following conditions:

Overloaded:
The tool is operated in a manner that causes it to draw an abnormally high current. In this situation, release the trigger switch on the tool and stop the application that caused the tool to become overloaded. Then pull the trigger switch again to restart.
Low battery voltage:
The remaining battery capacity is too low and the tool will not operate. If you pull the switch trigger, the motor runs again but stops soon. In this situation, remove and recharge the battery.

Switch action

CAUTION:

Before installing the battery cartridge into the tool, always check to see that the switch lever/trigger actuates properly and returns to the “OFF” position when released. To prevent the switch lever/trigger from accidentally pulled, the lock-off lever/button are provided. To start the tool, pull either switch lever or trigger.
For the switch lever, pull the lock-off lever and then pull the switch lever to start the tool.
For the switch trigger, depress the lock-off button and then pull the switch trigger to start to the tool. The lockoff button can be pressed from either right or left. The tool speed is increased by increasing pressure on the switch lever/trigger. Release the switch lever/trigger to stop.

NOTICE:
Do not pull the switch lever/trigger hard without pulling the lock-off lever/button. This can cause switch breakage.

Lighting up the front lamp (Fig. 3)

CAUTION:

Do not look in the light or see the source of light directly.
Pull the switch lever/trigger to light up the lamp. The lamp keeps on lighting while the switch lever/trigger is being pulled

ASSEMBLY

CAUTION:

Always be sure that the tool is switched off and the battery cartridge is removed before carrying out any work on the tool.

Installing or removing the saw blade

CAUTION:

Always clean out all chips or foreign matter adhering to the blade, blade clamp and/or slider. Failure to do so may cause insufficient tightening of the blade, resulting in a serious injury.

For Model JR100D (Fig. 4)

Insert the recipro saw blade into the blade clamp as far as it will go. The blade clamp sleeve rotates and the saw blade is fixed. Make sure that the saw blade cannot be extracted even though you try to pull it out.

CAUTION:

If you do not insert the saw blade deep enough, the saw blade may be ejected unexpectedly during operation. This can be extremely dangerous.

NOTE:

You can not use the jig saw blade with JR100D. (Fig. 5) To remove the saw blade, rotate the blade clamp sleeve in the direction of the arrow fully. The saw blade is removed and the blade clamp sleeve is fixed at the released position.

NOTE:

If you remove the saw blade without rotating the blade clamp sleeve fully, the sleeve may not be fixed. In this case, rotate the blade clamp sleeve fully, then make the sleeve fixed at the released position.

For Model JR102D

makita-JR100D-Cordless-Recipro-Saw-fig-7
To install the saw blade, loosen the bolt by hex wrench. When installing a recipro saw blade, press the bolt with the hex wrench to open the slot during inserting the blade. (Fig. 6 & 7) You can use both jig saw blades (B type) and recipro saw blades according to your work. Insert the saw blade straight into the blade clamp and tighten it by hex wrench. Pull the saw blade lightly to make sure that the saw blade does not fall off during operation. To remove the saw blade, follow the installation procedure in reverse. (Fig. 8 & 9)

Hex wrench storage (Fig. 10)

When not in use, store the hex wrench. It is fixed by two projections as shown in the figure to keep it from being lost.

OPERATION

CAUTION:

Always press the shoe firmly against the workpiece during operation. If the shoe is held away from the workpiece during operation, strong vibration and/or twisting will be produced, causing the blade to snap dangerously.
Always wear gloves to protect your hands from hot flying chips when cutting metal.
Be sure to always wear suitable eye protection which conforms with current national standards.
Always use a suitable coolant (cutting oil) when cutting metal. Failure to do so will cause premature blade wear.
Press the shoe firmly against the workpiece. Do not allow the tool to bounce. Bring the saw blade into light contact with the workpiece. First, make a pilot groove using a slower speed. Then use a faster speed to continue cutting. (Fig. 12 & 13)
You can use the switch lever or trigger according to your work.

NOTE: If the tool is operated continuously until the battery cartridge has discharged, allow the tool to rest for 15 minutes before proceeding with a fresh battery.

MAINTENANCE

CAUTION:

Always be sure that the tool is switched off and the battery cartridge is removed before attempting to perform inspection or maintenance.
Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result.

To maintain product SAFETY and RELIABILITY, repairs, any other maintenance or adjustment should be performed by Makita Authorized Service Centers, always using Makita replacement parts.

Noise

The typical A-weighted noise level is determined according to EN60745:

Vibration
The vibration total value (tri-axial vector sum) determined according to EN60745:
Model JR100D

Work mode: cutting boards
Vibration emission (ah,B): 9.5 m/s2
Uncertainty (K): 1.5 m/s2
Work mode: cutting wooden beams
Vibration emission (ah,WB): 9.5 m/s2
Uncertainty (K): 2.5 m/s2

Model JR102D

Work mode: cutting boards
Vibration emission (ah,B): 8.0 m/s2
Uncertainty (K): 1.5 m/s2
Work mode: cutting wooden beams
Vibration emission (ah,WB): 7.0 m/s2
Uncertainty (K): 1.5 m/s2

The declared vibration emission value has been measured in accordance with the standard test method and may be used for comparing one tool with another.

The declared vibration emission value may also be used in a preliminary assessment of exposure

WARNING:

The vibration emission during actual use of the power tool can differ from the declared emission value depending on the ways in which the tool is used.
Be sure to identify safety measures to protect the operator that are based on an estimation of exposure in the actual conditions of use (taking account of all parts of the operating cycle such as the times when the tool is switched off and when it is running idle in addition to the trigger time)
