Frequently Asked Questions - RP350YDH HITACHI
How do I change the drill bit on my Hitachi RP350YDH?
To change the bit, first ensure the tool is unplugged. Pull back the chuck sleeve (SDS-plus) and insert the bit, then release the sleeve to lock it in place. For chisel bits, rotate the mode selector to the chisel position and insert as above.
What is the correct lubricant for the rotary hammer?
Use a high-quality grease specifically designed for rotary hammers, such as Hitachi grease or lithium-based grease. Apply a small amount to the SDS bit shank and into the chuck periodically.
Can I use the RP350YDH for chiseling?
Yes, this model has a chiseling mode. Rotate the mode selector switch to the hammer-only or chiseling position (depending on the icon) to enable chiseling. Use appropriate chisel bits.
Why is my rotary hammer not starting?
First check the power cord and plug for damage. Ensure the switch is in the 'on' position. If still not working, the carbon brushes may be worn out and need replacement. Also check the lock-on button is not stuck.

The Hitachi RP350YDH can drill up to 35 mm diameter in concrete using core bits, and up to 35 mm with solid bits. For steel, max is 13 mm, and for wood, max is 32 mm.
How do I clean and maintain the tool?
After each use, wipe the tool with a dry cloth. Clean air vents with a brush to prevent dust buildup. Periodically lubricate the chuck with grease. Replace carbon brushes when they are less than 5 mm long.
Is the RP350YDH suitable for heavy-duty daily use?

Where can I find spare parts for this model?
Spare parts such as carbon brushes, chuck, switch, and power cord are available from Hitachi authorized service centers or online parts retailers. Use genuine parts to ensure safety and performance.
What safety precautions should I take?
Always wear eye and ear protection. Use the side handle for stability. Ensure the workpiece is clamped. Avoid contact with hidden electrical wires or plumbing. Never use the tool without the depth stop when drilling.
How do I adjust the auxiliary handle?
Loosen the side handle clamp by turning it counterclockwise. Rotate the handle to the desired position, then tighten the clamp securely. The handle can be mounted on either side for convenience.
