Frequently Asked Questions - VR250D MAKITA

How do I install or remove the battery cartridge?

Always switch off the tool first. To remove, open the cover and press the buttons on both sides of the cartridge while pulling it out. To insert, align the tongue with the groove and slide it in until it clicks into place. Do not force it.

What is the effective range for air bubble removal?

The effective range is about ten times the diameter of the vibrating head, which is approximately 250 mm for this tool. Operate at equidistant intervals within this range.

What should I do if the tool makes abnormal noise or seems faulty?

Switch off the tool immediately. Inspect for breakage, cracks, or deformation. If you accidentally drop it, check carefully before resuming use. Contact a Makita Authorized Service Center for repairs.

Can I use this vibrator in wet concrete?

Yes, it is designed for concrete. However, be careful not to allow water or wet concrete into the tool itself. Do not let the tool fall into wet concrete. Clean thoroughly after use with a wet cloth.

How do I maintain the flexible shaft and vibrating head?

Do not crush, twist, or overly bend the flexible hose. After use, wipe off any wet concrete with a wet cloth. Pay extra attention to cleaning vents, switch area, and cover openings. Ensure tool is off and battery removed before maintenance.

What type of battery does the VR250D use?

It uses a Makita 12V slide-type battery cartridge (sold separately). Both Nickel Metal Hydride and Lithium-ion batteries may be compatible. Always use genuine Makita batteries and chargers.

How long should I vibrate the concrete in one spot?

Vibrate until the concrete stops shrinking and the mortar rises evenly to the surface. Avoid vibrating too long in a single place to prevent segregation. The process is complete when the surface appears light and even.

What safety precautions should I take while operating?

Always keep your hands and face away from the vibrating head. Wear ear protection as noise may exceed 85 dB(A). Do not carry the tool with your finger on the switch. Do not set it down while switched on. Ensure the battery is locked properly.

Can I use this tool to move concrete within a form?

No, do not use it to move concrete; it will cause segregation. The mortar will move away and leave coarse aggregate behind. Use it only for removing air bubbles.

How do I store the tool and battery?

Store in a location where temperature does not exceed 50°C (122°F). Always cover battery terminals with the battery cover when not in use. If not using the battery for more than six months, charge it (for NiMH) before storage.

IMPORTANT SAFETY INSTRUCTIONS FOR CHARGER & BATTERY CARTRIDGE

ENC004-1

1. Before using battery cartridge, read all instructions and cautionary markings on (1) battery charger, (2) battery, and (3) product using battery.

2. Do not disassemble battery cartridge.

3. If operating time has become excessively shorter, stop operating immediately. It may result in a risk of overheating, possible burns and even an explosion.

4. If electrolyte gets into your eyes, rinse them out with clear water and seek medical attention right away. It may result in loss of your eyesight.

5. Always cover the battery terminals with the battery cover when the battery cartridge is not used.

6. Do not short the battery cartridge:

(1) Do not touch the terminals with any conductive material.
(2) Avoid storing battery cartridge in a container with other metal objects such as nails, coins, etc.
(3) 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.

1. Do not store the tool and battery cartridge in locations where the temperature may reach or exceed 50° C ( 122° F).

2. 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.

3. Be careful not to drop or strike battery.

SAVE THESE INSTRUCTIONS.

Tips for maintaining maximum battery life

1. Charge the battery cartridge before completely discharged. Always stop tool operation and charge the battery cartridge when you notice less tool power.

2. Never recharge a fully charged battery cartridge. Overcharging shortens the battery service life.

3. 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.
4. Charge the Nickel Metal Hydride battery cartridge when you do not use it for more than six months.

ADDITIONAL SAFETY RULES FOR TOOL

1. Always keep your hands and face away from vibrating head when operating.
2. Switch off the tool immediately if you notice abnormal noise or something faulty during operation.
3. Inspect the tool carefully for breakage, cracks or deformation if you accidentally drop it or strike it against something.
4. Do not charge the battery cartridge in locations where lacquer, paint, benzene, thinner, gasoline, gas or adhesive are stored/used.
5. Do not charge on cardboard or paper, cloth or bedding, straw mats, carpeting, vinyl or the like.
6. Do not charge in a dusty place or where lint accumulates.
7. Do not allow pieces of metal, water or other foreign objects to get into the charger port where the charging terminals are located.
8. Do not carry the tool with finger on switch.
9. Do not set the tool down and switch it on. The vibrating head may whip around out of control and cause an accident.
10. Be careful not to allow water, wet concrete or the like to get into the tool. Do not let the tool fall into wet concrete.
11. Insert the vibrating head carefully between iron/steel frames or reinforcing rods not to come in contact with them.
12. Do not crush or twist the flexible hose.
13. Do not overly bend the flexible hose.
14. Use a wet cloth or the like to carefully wipe off any wet concrete left on the tool after use. Extra care should be given to thorough cleaning of the vents, switch area, cover openings, etc.

OPERATING INSTRUCTIONS

Installing or removing battery cartridge (Fig.1)

• Always switch off the tool before insertion or removal of the battery cartridge.
• To remove the battery cartridge, open the cover and withdraw the battery cartridge from the tool while pressing the buttons on both sides of the cartridge.
• To insert the battery cartridge, align the tongue on the battery cartridge with the groove in the housing 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 inserting the battery cartridge. If the cartridge does not slide in easily, it is not being inserted correctly.

Switch action (Fig. 2)

CAUTION:

Before inserting the battery cartridge into the tool, always check to see that the switch trigger actuates properly and returns to the "OFF" position when released.

To start the tool, simply pull the trigger. Release the trigger to stop.

Operation (Fig. 3)

Hold the tool straight when inserting/operating. Use the tool within the effective vibration range at equidistant intervals. The effective air bubble removal range is about ten times the diameter of the vibrating head, or around 250 mm with this tool.

Do not use this tool to move concrete within a form. The mortar will just move away and the coarse aggregate will remain, causing segregation.

Effective leveling and removal of air bubbles

Removal of the air bubbles is complete after you have worked the tool throughout each effective range, the concrete stops shrinking, and the mortar has risen evenly to the surface, giving off a light appearance. Gently remove the operating tool not to leave holes.

NOTE:

• Vibrating too long in a single place causes concrete segregation.
• When the coarse aggregate segregates when placing concrete, shovel out the coarse aggregate and put it where there is plenty of mortar. Then use the tool on it. Don't leave coarse aggregate in the segregated condition.

When concreting a slope site, always pour from the bottom at the beginning. This way the weight of the freshly poured concrete and vibration will lead to effective removal of air bubbles. (Fig. 4)

Conversely, if the pouring is done first from above, the mortar will separate and eventually slide to the bottom.

MAINTENANCE

CAUTION:

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

To maintain product safety and reliability, repairs, maintenance or adjustment should be carried out by a Makita Authorized Service Center.
