ELECTRIC MOTOR
The motor installed on Foster model trimmers is equipped with permanently
lubricated, sealed ball bearings. No lubrication or maintenance is required.
DOOR SECURE
When closing and securing the door, do NOT tighten the door secure knob. It is
only necessary for the door to "touch" the base casting for a leak free fit. Over
tightening may cause leakage.
USE PLENTY OF WATER
The use of an adequate amount of water while trimming will keep the wheel
clean and cutting. An inadequate volume of water will result in a clogged
unusable wheel.
CHECK THE WATER SPRAY TUBE
It's a good idea to occasionally check the water spray tube to be sure all holes
are open. A straighten paper clip is useful in opening plugged holes.
WATER VALVE
The brass water valve located on the door of the model trimmer is intended to be
used as a flow control only, and not intended to be used as a water shut-off
valve.
MODEL AND SERIAL NUMBER
When ordering parts or requesting service always give the machine model
number and serial number which are inscribed on the identification plate located
on the front of the Lab Master Model Trimmer.
EXCESSIVE VIBRATION
Excess vibration from your model trimmer is a result of one or both of the
following:
1. An imbalance in the aluminum back plate as a result of accumulation of
plaster and stone on the back.
2. An out-of-balance abrasive wheel due to stone build-up and/or wear, or an
improperly balanced or non-balanced wheel. NOTE: Abrasive wheels
purchase from us are precision balanced for smooth running. This is done by
removing a portion of the heavy edge. As a result of the balancing process
the wheel may be out-of-round, but is in balance.
To determine and correct an imbalance follow this procedure:
1. Remove the abrasive wheel from the model trimmer, close and secure the
door, and turn the model trimmer on with the wheel removed. If the vibration
has ceased, the problem lies with the grinding wheel, and a replacement is
needed. NOTE: Sometimes the center mounting devise of the wheel (P/N
M095 - Lock Button) is worn and does not center the wheel properly. A wheel
that is mounted off center will also cause vibration. To check the Lock Button,
remove it together with the wheel, and check it's fit in the center hole of the
