qAdjusting Chain Tension

If the drive system makes loud noises, slips or makes grinding sounds while turned on, this indicates the drive chain is probably making the noise. This can be caused by the chain being adjusted too tight during assembly or coming loose from normal wear-and-tear.

WARNING: Practice in an open area free from obstacles until you are familiar with the brake function. DO NOT RUN OVER ANY OBJECT AS IT COULD DAMAGE THE BRAKE OR DRIVETRAIN.

WARNING: To avoid a pinch or injury, keep fingers away from moving sprockets and chain.

The chain drive system consists of the drive-shaft sprocket (A), the chain (B), the adjusting bolt (C), the motor sprocket (D).

1 Using a 16mm open wrench, loosen the chain jack-screw locknut

(B)and tighten or loosen the adjust- ing bolt (A) to tighten or loosen the chain as needed.

Note about chain adjustment: The chain should not be under tension nor floppy loose. There should be about 3/8-inch (10mm) of slack. BE CAREFUL NOT TO ADJUST TOO TIGHT. The tensioning system can easily impart too much tension and snap the chain or bend the motor output shaft. Turn the adjusting bolt by hand 1/8 to 1/4 turn or less at a time and recheck the adjustment each time.

2 Once the adjustment is good, while holding the adjusting bolt, retighten the locknut securely. Test ride the Ground Force and readjust as needed.

Note: If the locknut is not tightened properly, the adjustment will vibrate loose from normal use.

Note: The motor cover does not need to removed for this adjustment procedure. The chain adjustment can be checked by tipping the Ground Force on it’s side and reaching under the cover (with power switched OFF). However, for the first time you make this adjustment we recommend you remove the cover to see exactly what is happening.

Note: Proper alignment of the chain must be maintained. If the chain

is adjusted properly, but is noisy or rough running, check alignment of the sprockets. The drive-shaft sprocket can be adjusted slightly from side-to-side by loosening the set screw. Note that a key maintains the drive position to the shaft.
