Belt Installation & Adjustment
Removal
Remove the top cover by unscrewing the two 8mm bolts
either side of the chassis. Loosen the engine/motor mounting
plate bolts and slide the engine/motor forward. Slide the belt
off the drive pulley and then remove it from the engine/motor
pulley.
Installation
Slide the new belt onto the engine/motor pulley first, locating
the belt in the pulley’s teeth. Then slide onto into the teeth of
the drive pulleys.
Slide the engine/motor backwards until the slack in the belt is
taken up, gently nip the four bolts and ensure the slack in the
belt is correct (see note below). If the tension needs adjusting
move the motor mounting plate in the desired direction until
the correct tension is achieved. (see P.10, Pre-Start Check for
detail) Tighten all engine/motor mounting plate bolts fully,
refit the top cover and tighten the 8mm bolts.
Drive system maintenance
The drive system on the TCG250 is virtually maintenance free
and will give a long service life without attention providing the
belt tension is set correctly.
The belt may need changing occasionally, the bearings (29)
will require greasing after any lay up period and/or every 6
months or occasionally during heavy use.
Long period storage: over 3 months
Clean outside of machine, inspect the grinding blocks for
wear; replace any worn parts as required.
Remove any build up of material from inside of grinding disc
area following step in start of “Grinding Block Replacement”
Section. Cover the machine to protect it. Store the machine
in a dry place. Be sure to check security of wooden wedges
after any lay up period.
shut down
On electric-powered machines, simply release the “deadman’s
handle” button. On engine-powered machines, move the
engine’s throttle lever to the slow speed position. (This
avoids the engine becoming washed internally by neat fuel if
switched off from high engine revolutions.) Release the ‘hold
to run’ lever and on Honda engines, switch off the engine’s
start switch.
On both electric and engine-powered machines, use the
stand (operation of which is described on page 10, Starting)
to raise the disc off the ground to prevent any built up heat
deforming the rubber coupling if it is left under load whilst hot
and stationary. The machine can be stored whilst on its stand.
After the engine or motor has completely cooled, clean off
any concrete dust from external components and remove
any heavy build up of concrete dust from inside the front dust
skirt, (see start of “Grinding Block Replacement” section for
safe method of gaining access to inside of front dust skirt).
Take care when using hoses or pressure washers and clean
within the dust skirt area only.
Do not to allow water to be directed at or splashed onto the
engine, electric motor or any electrical components. Once
clean and dry, cover the machine to protect it and store the
grinder in a dry place.
IMPORTANT! Close the engine fuel tap
IMPORTANT! Normal slack should be approximately
13mm (1/2”) when the belts are depressed in the middle
position between the engine pulley and driveshaft
pulley.
This machine is specifically produced for use on concrete and
steel floors. Do not modify, add components to or retrofit the
unit in a way which could affect its safety and do not use
non-official accessories. This is not allowed. A full range of
genuine parts are available to purchase. Do not use machine
in water.
