OPERATION
Assembly
1. Remove grinder and other parts from the box.
2. Stand the grinder on firm and level surface.
3. Fit eye shield assembly to dry wheel guard using bolt, flat washer and spring washer.
4. Fit tool rest to dry wheel guard using flat-head bolt, washer and plastic thumb nut.
Operation
Secure grinder to firm, level surface before using. Positioning the grinder towards the front edge of
the bench will facilitate the handling of long tools. If possible, leave a space to the left hand side of
the machine for easy access to the wet wheel. An alternative method is to secure the grinder to a
sheet of plywood, which can then be clamped to a bench or table to present the grinder in the most
convenient position.
Before using the dry wheel ensure that the spark guard (behind the eye shield) is positioned as close
to the surface of the wheel as possible and that the eye shield is in a position to prevent sparks
flying up. Wear safety spectacles when working on a grinder.
The dry wheel can be used for grinding profiles or bevels on virtually any cutting tool; plane irons,
chisels, gouge, turning tools, drill bits, etc. The aluminium oxide wheel will cut cleanly and without
undue heating of the tip of the tool. However, care should be taken not to grind a tool too hard or
for too long in case over-heating occurs. Final sharpening of the edge should be carried out on the
wet wheel.
Before using the wet wheel fill the water trough with clean water to a level just below the top edge
of the trough. The wet wheel will cut more slowly than the dry wheel but, because it is running
more slowly and is water-cooled, it will produce a fine edge without any risk of burning. Tools can
either be sharpened free-hand or, in the case of those with a long cutting edge such as knives, can be
located on the notches on the edges of the trough in order to maintain a constant grinding angle.
MAINTENANCE
WARNING! Turn the power switch “OFF” and disconnect the plug from the outlet prior to
adjusting or maintaining the grinder. DO NOT attempt to repair or maintain the electrical
components of the motor. Take the grinder to a qualified service technician for this type of
maintenance.
Maintenance Required
1. Check power cord before each use.
2. Check wheels for cracks before each use.
3. Check moving parts for alignment and binding issues before each use.
4. Check tool rests and spark deflectors for spacing from wheels before each use.
5. Adjust tool rests and spark deflectors as needed.
6. Dress grinding wheels as needed.
7. Replace grinding wheels as needed.
8. Clean and vacuum dust from the motor housing and other grinder parts as needed.
Service beyond recommended maintenance on these tools should only be performed by an
authorised service centre.
