Adjusting the Transmission Belt Tension through the Drive Control
Cable
The Drive Belt will stretch a little when new, then more over time. If the
Trimmer does not move forward with the Wheel engagement Bar engaged,
adjust the Trimmer Drive Cable to put more tension on it. The Adjustment Jam
Nuts are located at the upper end of the Drive Cable itself.
1. Locate the end of the Drive Cable along the right Handlebar. There are Jam
Nuts threaded onto the Cable Threads.
2. Adjust the Jam Nuts towards the end of the Cable to tighten the Belt tension
or towards the sheathing of the Cable to loosen the tension of the Belt
(
Figure 42 ).
Note : The Drive Cable should be adjusted so the Bar will pull close to the Handlebar but not completely against it without feeling
extreme tension.
Battery Care (Electric-Start Models)
Proper care can extend the life of a battery. Follow these recommendations to ensure best performance and long life:

Before charging the Battery, observe its external appearance and keep it clean and dry. Never charge or use a Battery that
shows cracks, changes shape, leaks, or is otherwise obviously damaged.

Do not allow the Battery to run down completely before charging. Leaving the Battery discharged damages the Battery . If the
machine is not used, charge the Battery every 4 to 6 weeks. Operate the Engine for at least 45 minutes to maintain proper
Battery charge.

Store an unused Battery in a dry environment with temperatures b40°F (5°C) and +95°F (+35°C). Make sure the
storage temperatures will never be outside of these limits. The lower the storage temperature is within the specified
temperature, the better as the battery will discharge more slowly at lower temperatures.

Do not charge an already charged Battery. In theory, you cannot overcharge our Battery with a trickle charger; however, when a
Battery is fully charged and the charger is still on, it generates heat that could be harmful to the Battery. A fully charged Battery
will read 12V-13.2V with a voltmeter.

Do not continue to crank the Engine when the Battery charge is low.

If the Battery begins to leak, avoid contact with the leaking acid. Place the damaged Battery in a plastic bag, then dispose of it
properly.
Charging the Battery
Operate the Trimmer Engine for at least 45 minutes to maintain proper Battery charge. If the Battery loses its charge, you will
need to use a trickle Charger to recharge it. The Charger should have an output of 12 volts at no more than 2 amps.

At 1 amp, the Battery may need charging for as long as 48 hours.

At 2 amps, the Battery may need charging for as long as 24 hours.
Note: Using the recoil starter and then running the Engine will not recharge a dead or significantly discharged Battery.
To connect a Battery Charger to your TRIMMER/MOWER, follow the steps listed below.
3. Detach the two Battery wires going to the Battery on your TRIMMER/ MOWER.
If battery acid does contact your skin or eyes, flush with cool water for at least 15 minutes and call a physician. If you ingest acid,
call a physician immediately.
