Windsor GH3 manual Daily Maintenance, Servicing The Grouthog, Brush Removal, Belt Replacement

DAILY MAINTENANCE

1.Before storing the machine, clean exterior. Remove brush and rinse clean with hot water.

2.Periodically inspect electrical cable and connections. Because the cable will lie on wet, abrasive floors, the cable must be well insulated. If the insulation is broken or frayed, repair or replace immediately.

3.Remove wheels periodically and apply silicone lubricant to the axle.

SERVICING THE GROUTHOG

Always disconnect the power cord from electrical

source before making repairs or adjustments.

BRUSH REMOVAL

1.Place handle in upright position. Tilt machine back with handle resting on floor.

2.Loosen Knob Assembly (item 20) holding the left bearing block (item 29).

3.Remove bearing block from the frame and brush core.

4.Remove brush (item 33) from the right bearing block (item 38). When re-installing the brush, make sure that the guide pins (item 30) on both ends are properly aligned with the holes in the brush core and the bearing block (items 29) is correctly seated.

BELT REPLACEMENT

1.Remove main cover (item 73 held on by (4) screws). Remove bottom belt guard (item 34 held on by (2) screws).

2.Using an allen wrench, remove the screw holding the right bearing block (item 56).

3.Remove bearing block along with the old belt. Replace belt and bearing block. Check belt for proper tension and alignment (see Motor Replacement for belt adjustment).

MAINTENANCE

BEARING REPLACEMENT

Using a small torch, heat the aluminum bearing block just enough to allow the bearing and shaft (items 31 and 32, respectively) to be removed.

Use a bearing puller to remove old bearing. When replacing bearing, use a socket or metal sleeve just large enough to slip over the shaft and still contact the inner bearing race. Use an arbor press or vise to press new bearings on shaft. Re-heat aluminum block just enough to allow re-assembly of bearing and shaft.

Do not overheat block as this will damage the bearing.

MOTOR REPLACEMENT

1.Remove motor cover (item 73 held on by (4) screws).

2.Remove (4) screws holding motor (item 60). Disconnect motor lead and remove motor.

3.When re-installing the motor use a straight edge to realign pulleys. A screw driver can be used to adjust tension.

4.NOTE: Belt should be adjusted to snug fit to prevent slipping. DO NOT OVERTIGHTEN.
