1. There is one Grease Fitting below the black Belt Guard that needs lubrication
(Figure 13):
• The Belt Idler Arm should have 1-2 pumps of Grease every 25 operating
hours.
NOTE: Over greasing will cause grease to leak out of the seals onto the Mower Drive
Belt. Unless instructed otherwise, pump only until you feel slight resistance
(1-2 pumps).
2. You should lubricate the Drive Chain with SAE 30 oil every 25 operating
hours—more often if you operate the machine in extremely dusty or wet
conditions. Remove the Chain Cover, lubricate the Chain, and replace the
Cover (Figures 14 & 15).
3. Place the Differential Lock In/Out Lever in the OUT position.
4. Clean the Lock In/Out Sleeve Shaft and Groove of any accumulated grass
and debris with a cloth and lubricate the Shaft and Groove using SAE 30 oil
(Figure 16).
5. Move the Differential Lock In/Out Lever back and forth a few times to
distribute the lubricant on the Lock In/Out Sleeve Shaft and Groove.
Removing and Replacing the Belts
To Replace the Blade Belt
1. Remove the black Belt Guard by unscrewing the black Knob, lifting the
Cover, and pulling up and back to remove it.
2. Release the Belt Tension Lever (Figure 17).
Use only DR belts on your machine. They have been thoroughly tested and
proven for many hours of use.
Before performing any maintenance procedure or inspection, stop the
engine, wait five (5) minutes to allow all parts to cool. Disconnect the spark
plug wire(s), keeping it away from the spark plug(s).
