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. DO NOT operate Hole
Digger without rubber boot in proper location or in poor condition to
prevent foreign material accumulation within throttle control assembly.
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.

NOTE: Screw bit for 50.8 mm and 76.2 mm (2 and 3 inch) diameter augers
functions as boring head. No other blade is used.
NOTE: Replacement of auger screw bit will require a level working platform of
appropriate size and weight.
1.
Inspect auger for excess wear and/or damage. A replacement screw bit
will not allow auger with excess wear and/or damage to properly dig.
2.
For 50.8 mm and 76.2 mm (2 and 3 inch) diameter augers, use hammer
and straight-type punch to remove roll pin and screw bit.
3.

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 back to service.
REPLACING WORN AUGER BLADE
Application: All 2350 Series augers 101.6 mm (4 inch) through 203.2 mm
(8 inch) diameter augers.
Tools Required:
1 each, safety glasses
2 each, 12 mm (7/16 inch) wrenches
Parts Required:
1 each, PN E244, 101.6 mm (4 inch) diameter auger blade

Augers with only one capscrew visible and/or usable is worn beyond useful
service life and must be discarded.
1.
Replacement of auger blade will require level working platform of
appropriate size and height.
2.
Using 12 mm (7/16 inch) wrenches, loosen capscrews to remove worn
blade from auger plate. Remove any accumulated dirt from auger plate
area. Install replacement blade with capscrew threads facing up toward
auger hub. Tighten firmly with wrenches.
NOTE: Replacement blade will extend past outside diameter of auger plate for
added component wear protection.
3.
Return auger back to service.
