Section 4 - REPAIR & ADJUSTMENTS
WARNING
DO NOT attempt any maintenance, adjustments or
service with engine and blade running. STOP engine
and blade. Remove key. Disconnect spark plug wire
and secure away from spark plug. Engine and
components are HOT. Avoid serious burns, allow
sufficient time for all components to cool. Wear
heavy leather gloves when handling or working
around cutting blades. Blades are extremely sharp
and can cause severe injury.
4.1 MOWER BLADE REPLACEMENT
4.1.2. BLADE SHARPENING
(Continued From Previous Page)
4. Sharpen blade on a grinding wheel at an angle of 22
to 28 degrees. DO NOT sharpen blade beyond original
cutting edge. See Figure 4.3.
FIGURE 4.3
5. Check blade for balance. If necessary, correct
balance by grinding heavy end of blade.
6. Reinstall blade. See Figures 4.2 & 4.3. Check
torque of blade retaining cap screw. Recommended
torque should be 30 to 40 ft. lbs.
4.2 WHEEL DRIVE CONTROL ADJUSTMENT
1.
To check wheel drive control for correct
adjustment, hold blade control against upper handle
and pull wheel drive control backward slightly to
remove any slack in wheel drive control cable. The
wheel drive control is properly adjusted when the
two 1/8” diameter holes, located at the connection
point of wheel drive control and the blade control are
aligned. See Figure 4.4.
2. If holes are not aligned, follow procedure in Step 1
hold both controls in that position. See Figure 4.5.
FIGURE 4.4
IMPORTANT: If machine creeps forward after wheel
drive control is released the cable is too tight and must
be readjusted to eliminate all forward movement.
Machine must not have any forward movement when
wheel drive control is disengaged. If the wheel drive
control fails to return quickly to the “OFF” position when
released, check for a broken, binding, or kinked cable.
