4. If the engine has an oil filter, remove the old Oil Filter with an Oil Filter Wrench and replace with a new Oil Filter as described
in the Engine Operator Manual.
5. Replace the Oil Drain Hose Assembly onto the Storage Hook and close the Oil Drain Cap. Replace the Oil as described in the
Engine Operator Manual.
Cable lubrication
Supplies Needed:
Multi-purpose Teflon Aerosol Lubricant
Lubricate the Traction Drive Cable, Shift Cables, Throttle Cable and Brake Cables where the Cable goes into the Sheathing with a
Multi-purpose Teflon Aerosol Lubricant
1. Spray the lubricant into the Cable Housing while working the Cable back and forth a few times. Perform this lubrication more
often in dry and dusty environments.
Idler Arm Lubrication
Tools & Supplies Needed:
Grease Gun w/General Purpose Grease
There is one Grease Fitting below the black Belt Guard to lubricate (Figure 30)
With the Blade Belt removed (Refer to “Removing the Brush Deck” on page 17),
move the idler arm to make sure it rotates freely. If resistance is felt when
pivoting the arm please lubricate as follows:
1. Remove the knob and belt guard from the deck.
2. Locate the Grease Fitting on the idler arm.
3. Using the grease gun add a small amount of grease (1-2 pumps or until
slight resistance).
Note: Over greasing may cause grease to leak onto the Mower Drive Belt.
4. Reinstall the Belt (if removed) and Belt Guard.
Adjusting the Traction Drive Cable
Note: When properly adjusted, tension on the Traction Drive Lever should increase
when the Lever is about parallel to (almost touching) the Handlebar Grip.
1. Locate the Traction Drive Cable along the right Handlebar (Figure 31). There
is an In-Line Adjuster to change the length of the Cable.
2. Rotate the center portion clockwise while holding the ends stationary to
expand the In-Line Adjuster and remove slack from the cable.
Adjusting the Shift Cables
If there is a lot of “play” in the Wheel Speed Lever or if the lever is no longer aligned
with the Wheel Speed Label, you may need to adjust the Shift Cables.
Tools needed:
Two 13mm Wrenches
1. Locate the Shift Cable Adjustment Nuts on the Shift Lever end of the cable
(Figure 32).
2. Loosen one of the Cable Jam Nuts on the cable using two 13mm Wrenches.
3. Pull down slightly on the cable just enough to pull out the slack and then
tighten the Cable Adjustment Nut to hold the cable housing in tension. You
may need to tension one cable while loosening the other to realign the Lever.
Note: Do not over tighten the cable. It will create a spongy feel in the shift lever.
