MAGURA® THROTTLE CONTROL MAINTENANCE PROGRAM
For every 8 hours of actual operation and whenever throttle cable is replaced,
the following maintenance program is to be followed:
1. Remove plastic cover to properly inspect internal components. If
damaged or worn, replace. FIGURE 18
FIGURE 18
2. Inspect idler pulley. Normal use will produce a wear pattern into idler
pulley by throttle cable. Maximum allowable groove wear depth created
by cable is 0.045 inch (1.1 mm). Wear depth in excess of this limit
requires idler pulley replacement.
3. Inspect throttle cable for excessive wear and fraying of area in direct
contact with idler pulley. Abnormal wear or fraying requires replacement
of throttle cable.
4. Inspect barrel end of throttle cable for proper retention. Properly retained
barrel end will have no relative movement between it and inner cable.
Any relative movement requires throttle cable replacement. FIGURE 19
FIGURE 19
5. Inspect receptacle area of throttle control which retains barrel end of
throttle cable. Properly fitted barrel fitting should have complete freedom
of movement with no binding restrictions or excessive play due to wear.
Barrel fitting which is binding within receptacle requires throttle cable
replacement. Excessive receptacle wear requires specific component
assembly replacement. FIGURE 20

6. Apply appropriate preservative to rubber boot assembly to protect internal
components from foreign material accumulations.
7. If regular throttle control inspection determines carburetor return spring
does not properly return to engine cut-off position, remove throttle control
grip tube from throttle control handle. Inspect tube and operator handle
surface area for accumulation of foreign material, including dirt, moisture,
etc. Remove any accumulation, clean as necessary. DO NOT apply
external lubrication to this area during reassembly process.
8. Inspect throttle control grip proper attachment to throttle control
assembly. Replace grip which fits loose or has become worn/damaged.
REPLACING WORN AUGER SCREW BIT
Application: All 1 inch diameter drive auger bits.
Tools Required:
1 each, safety glasses
1 each, hammer (if required)
1 each, 1/4 inch diameter straight-type punch (if required)
2 each, 1/2 inch (12.7 mm) wrenches
Parts Required:
1 each, PN BR10636 Auger Screw Bit for 3 inch (76.2 mm) diameter auger bit.
1 each, PN BR10637 Auger Screw Bit for 2 inch (50.8 mm) and 4 inch (101.6
mm) to 8 inch (203.2 mm) diameter auger bits.
1 each, PN 20051000 Roll Pin for 2 inch (50.8 mm) and 3 inch (76.2 mm)
diameter auger bits if required.
1 each, PN 15051300 Bolt for 4 inch (101.6 mm) to 8 inch (203.2 mm)
diameter auger bits, if required.
1 each, PN 52050000 Nut for 4 inch (101.6 mm) to 8 inch (203.2 mm)
diameter auger bits, if required.
NOTE: Screw bit for 2 and 3 inch diameter auger bits functions as boring head.
No other blade is used.
NOTE: Replacement of auger bit screw bit will require a level working platform
of appropriate size and height.
1. Inspect auger screw bit for excess wear and/or damage. A worn screw bit
with excess wear and/or damage will not allow auger bit to properly dig.
2. For 2 and 3 inch diameter auger bits, use hammer and straight-type
punch to remove roll pin and screw bit.
3. For 4-inch diameter auger bit and above, use 1/2 inch (12.7 mm)
wrenches to remove bolt and screw bit.
4. Insert replacement screw bit, align holes and reinstall applicable roll pin
or bolt and nut with appropriate tools.
5. Return auger bit back to service.
DANGER
• Wear safety eyewear and other safety apparel appropriate
for the job application and/or job site environment.
• Screw bit replacement process can create flying steel
chips and/or other debris.
• Caution all onlookers regarding the possibility of and/or
to remain clear of flying debris.
• Improper safety procedures can result in property
damage and/or personal injury.
CAUTION
• DO NOT operate Auger without rubber boot in proper location
or in poor condition.
• Without boot assembly, foreign material can accumulate
within throttle control assembly.
• Such an occurrence can restrict movement of internal
components, reducing operator control of Auger and result in
property damage and/or personal injury.
