Frequently Asked Questions - 51-202 RIKON

How do I change the sanding paper on the RIKON 51-202?

The sander uses a hook-and-loop (Velcro) pad. Simply peel off the old paper and press a new sheet of matching size onto the pad. Ensure the holes align for dust collection.

What is the variable speed range and how do I adjust it?

The speed ranges from 4,000 to 12,000 OPM. Use the dial on the top of the sander to set the desired speed. Lower speeds are for delicate surfaces, higher speeds for aggressive material removal.

Can I use the sander without the dust bag?

Yes, you can attach a vacuum cleaner hose to the dust port for more efficient dust extraction. The dust bag is included but optional.

How do I clean the dust collection system?

Empty the dust bag frequently and tap it clean. For the vacuum adapter, ensure the port is free of debris. Do not use water; use compressed air or a brush.

What size sandpaper does the RIKON 51-202 use?

It uses 113 x 102 mm (4.5 x 4 inch) hook-and-loop sheets. Most standard orbital sander papers of that size are compatible.

Is the RIKON 51-202 suitable for drywall sanding?

It can be used for drywall with fine grit paper and a vacuum attachment to control dust. However, for extensive drywall work, a dedicated drywall sander is recommended.

How do I replace the carbon brushes?

Unplug the sander. Locate the brush caps on each side of the motor housing, unscrew them, and remove the old brushes. Insert new ones (same size) and tighten caps. Brushes wear out over time and require periodic replacement.

What does the lock-on button do?

The lock-on button allows continuous operation without holding the trigger. Press the button while the sander is running to engage; press the trigger again to release.

Why is my sander vibrating excessively?

Excessive vibration may be due to worn sandpaper, unbalanced paper, or a loose pad. Check that the paper is properly attached and not worn out. If problem persists, inspect the pad for damage.

Can I use the sander for wet sanding?

No, the RIKON 51-202 is designed for dry sanding only. Moisture can damage the motor and create electrical hazards. Use wet/dry sanding paper only with a compatible sander.

A moment of inattention while operating power tools may result in serious personal injury.

1. ALWAYS WEAR A DUST MASK TO PREVENT INHALING DANGEROUS DUST OR AIRBORNE

PARTICLES, including wood dust, crystalline silica dust and asbestos dust. Direct particles away from face and body. Always operate tool in well ventilated area and provide for proper dust removal. Use dust collection system wherever possible. Exposure to the dust may cause serious and permanent respiratory or other injury, including silicosis (a serious lung disease), cancer, and death. Avoid breathing the dust, and avoid prolonged contact with dust. Allowing dust to get into your mouth or eyes, or lay on your skin may promote absorption of harmful material. Always use properly fitting NIOSH/OSHA approved respiratory protection appropriate for the dust exposure, and wash exposed areas with soap and water.

1. USE A PROPER EXTENSION CORD IN GOOD

CONDITION. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. The table on the following page shows the correct size to use depending on cord length and nameplate amperage rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the larger diameter of the extension cord. If in doubt of the proper size of an extension cord, use a shorter and thicker cord. An undersized cord will cause a drop in line voltage resulting in a loss of power and overheating.

USE ONLY A 3-WIRE EXTENSION CORD THAT HAS A 3-PRONG GROUNDING PLUG AND A 3-POLE RECEPTACLE THAT ACCEPTS THE TOOL'S PLUG.
