Sealey SMS2107 - Manual (Page 3)

6.1. PRE-USE INSPECTION
 WARNING! Inspect the machine before each use. Ensure that it is disconnected from
the mains before carrying out any inspection or maintenance.
6.1.1. Check that the tool rest on the dry wheel is securely fixed and set at a maximum of
2mm from the grinding stone.
6.1.2. Check that eye shield is in good condition, secure and that you can see through it clearly.
6.1.3. Turn the dry grinding stone by hand and check for any damage. Check they do not
touch the tool rest or guards and are correctly aligned.
If any of the above checks fail, replace, repair, or adjust as necessary before starting
the grinder.
6.2. STONE USE
IMPORTANT: Grinding stones MUST ONLY be assembled by a person holding a
grinding wheel certificate. See section 5.
6.3. USING THE GRINDER
 WARNING! Before commencing work, ensure you have read, understood, and
applied the section 1. Safety Instructions
6.3.1. Place the eyeshield in its appropriate safety location (see:4.1.1).
6.4. USING THE WET STONE
6.4.1. Fill the reservoir with water and adjust the valve to achieve the required flow rate.
6.4.2. Ensure that the drain tube is fitted and placed in a waste water container.
6.4.3. Place the blade to be sharpened in the tool holder (fig.7).slacken the clamp screws,
insert the blade and tighten.
6.4.4. If an angled cutting face is required, the horizontal angle guide may be set. This is
achieved by slackening the lock screw, moving the guide to the required angle and
tightening the lock screw.
6.4.5. When the blade is secured in the holder, set the tool rest to the required height and
angle. Connect to the mains supply, switch the machine on and offer the blade to the
wheel, hooking the lip of the tool holder over the tool rest (fig.8).
6.4.6. The blade is sharpened by moving the tool holder from side to side along the tool rest.
6.5.
USING THE DRY STONE
6.5.1. The dry stone can be used in the conventional manner by setting the tool rest as
in 4.2.
6.5.2. Alternatively, the tool holder assembly can be transferred from the wet stone to the
holder incorporated into the dry stone wheel cover (fig.9).The eyeshileld needs to be
folded out of the way.
6.5.3. In this position, the blade can be passed lightly across the circumference of the stone.

5.2. DRY STONE CHANGING PROCEDURE
 WARNING! Unplug grinder from the mains power supply before changing stone.
5.2.1. Remove the three cross head machine screws from the wheel cover and remove it.
5.2.2. Hold the grinding stone firmly. To protect your hands use cloth or wear gloves. Unscrew
the retaining nut (Fig.2.1).
Note: The nut on the wet and dry grinding wheels are left-hand threaded (undo clockwise). It may
be necessary to strike the wrench sharply in the loosening direction with the heel
of your hand to loosen the nut.
5.2.3. Remove the grinding stone (Fig.2.4), from the main spindle.
5.2.4. Inspect the new stone carefully before installing to ensure there are no fissures, chips, or
cracks.
Tap the grinding wheel gently with a rubber mallet and listen for a sustained high pitch (good)
or dull short sound (flawed).
 WARNING! DO NOT USE A DAMAGED STONE OR WITHOUT SUPPLIED BLOTTERS.
5.2.5 Inspect the blotters (fig2.3/2.5), if they are damaged replace them. The grinder must never
be used without blotters.
Use the blotters supplied by the wheel manufacturer only.
5.2.6 Install the new stone by reversing steps above. Ensure the domed washers (fig.2.2/2.6) are
installed with the flange on the inside, (i.e. the concave side against the blotter).
5.2.7 Hold stone steady and secure locking nut. DO NOT over tighten as this may crack the stone.
5.2.8 Replace wheel cover, re-adjust tool rest to a maximum of 2mm from stone face and tighten
securely.
5.3 WET STONE CHANGING PROCEDURE
5.3.1. Engage the wrench with the boss in the centre of the wet grinding wheel (fig.3), hold the stone
in a gloved hand and turn the boss in a clockwise direction to release.
5.3.2. Lift the stone from the drive shaft to remove.
5.3.3. When replacing the stone, ensure that the spacer (fig.4) is in place, mating with the flat on
the drive shaft.
5.3.4. Replace the stone over the spacer and secure with the boss, tightening in an anticlockwise
direction. Do not over tighten
