MAINTENANCE
Blade Sharpening
Blades may be sharpened by filing or grinding, but with either method the balance of the blades must be
maintained at 0.004 Nm or less. Failure to maintain balance causes excess vibration, wear and shortened life
of not only the blades, but most all components of the machine. To balance a blade after sharpening: attach
3.9 g of weight 127mm from center on the light end. This should make the light end the heavy end. If it does
not: File or grind the heavy end until the addition of weight makes the light end the heavy end.
Cutterdeck Pulley Assembly
BLADE RE-INSTALLATION
1.
Place the desired number of spacers (no more than
2) on the spindle bolt below the cutterdeck between
the blade and spindle shaft.
2. Insert the cutter spindle bolt (from bottom) complete
with washer, blade and spacers.
3. Place remaining spacer(s) on the spindle bolt above
the cutterdeck between the conical washer and nut
(as shown). Replace nut and tighten to 95 Nm.
SPARK PLUG
•
Remove plug and check condition.
•
Good operating conditions are indicated if the plug has a light grey or tan deposit. A white blistered coating
may indicate overheating. A black coating usually means an “over rich” fuel mixture caused by a clogged
air cleaner or improper carburetor adjustment. Do not sandblast, wire brush or otherwise try to clean a
dirty plug. Best results are obtained with a new plug.
•
See engine manufacturers manual for proper spark plug gap.
NOTE:
•
Do not overheat or weaken the blades.
•
Do not straighten bent blades. Replace with new
Ransomes blades.
If lift portion of blade is worn thin replace with a new
Ransomes blade.
•
ALWAYS replace with Ransomes blades—do not
use another manufacturer’s blades as this could be
dangerous.
•
Replace cracked or bent blades.
BLADE REMOVAL
1.
Use a box wrench or socket with a long breaker bar
to remove spindle bolt under cutterdeck.
2. Slip tube over breaker bar or wrench if necessary to
gain leverage.
3. Keep hands clear as blades may rotate when bolt
releases.
4. When changing blades, wear thickly padded gloves.
5. Block blades from turning by using a piece of wood.
6. Follow these instructions to prevent injury when bolt
releases.
NOTE: To prevent blade from turning, place block of
wood at A, with grain perpendicular to blade.
