Frequently Asked Questions - Expert 98427 Draper
What is the proper way to change sanding discs on the Draper Expert 98427?
To change the sanding disc, first ensure the sander is unplugged. The 98427 uses a velcro-backed pad. Simply peel off the old disc, align the new disc's centre hole with the pad, and press firmly to secure. Always use discs with dust extraction holes matching the pad's pattern.
Can this sander be connected to a dust extractor?
Yes, the Expert 98427 comes with a dust hose adapter that fits standard vacuum hoses (35 mm). Remove the dust bag and attach the adapter, then connect your vacuum. This ensures efficient dust removal and a cleaner work environment.
What speed setting should I use for different materials?
The 98427 has a variable speed control (12,000 - 14,000 OPM). Use lower speeds for plastic and paint removal to avoid heat damage. Use higher speeds for wood and metal to achieve faster material removal.
How do I maintain the sander for long-lasting performance?
Regular maintenance is essential. Keep the air vents free of dust, clean the dust bag after each use, and periodically check the carbon brushes for wear. Replace worn brushes promptly to prevent motor damage.
Is the Draper Expert 98427 safe to use?
Yes, it features double insulation and a locking switch to prevent accidental start. Always wear safety goggles and a dust mask, and ensure the workpiece is securely clamped. Unplug the tool before changing discs or performing maintenance.
What is the correct sanding technique for a smooth finish?
Use light pressure and let the sander work with its own weight. Move the sander in overlapping passes along the grain. Avoid staying in one spot to prevent gouging. Start with coarse grit and progress to finer grits.
Can I use this sander to remove paint or varnish?
Yes, the 98427 is suitable for removing paint and varnish from wood and metal. Use a coarse grit disc (e.g., 60-grit) at a lower speed to avoid clogging. Work in small sections and clean the disc frequently.
Why is the sander not running at full speed?
Possible causes include a blocked dust bag restricting airflow, worn carbon brushes, or the variable speed dial set too low. Check the power cord for damage, and ensure the trigger is fully pressed. If the issue persists, consult the manual.
What spare parts are available for this sander?
Common spare parts include sanding pads, carbon brushes, switch assemblies, and dust bags. These can be ordered from Draper approved retailers. Always use genuine parts to maintain safety and performance.
How should I store the sander when not in use?
Store the sander in a dry place away from moisture and direct sunlight. Coil the power cord loosely, and attach a protective cover to the pad to prevent debris from accumulating. Keep it out of reach of children.
