GENERAL MAINTENANCE
◾
Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use clean cloth to remove dirt, dust, oil, grease, etc. Insect
repellent spray may damage plastic and painted surfaces. Do not spray insect repellent near the mower.
◾
Prolonged exposure to sunlight will damage some surfaces.
◾
Once the mower is left out in the rain accidentally, use dry clean cloth to dry the seat, control panel, etc., before you
restart it or store it.
WARNING: Do not at any time let brake fluids, gasoline, petroleum-based products, penetrating oils, etc., come in
contact with plastic parts. Chemicals can damage, weaken or destroy plastic which may result in serious personal injury.
Cleaning the machine
Remove any build-up of grass and leaves on or around the mower housing. Wear eye protection and use compressed air
after each use to clean the mower housing or the top side of the mower deck.
The underside of mower deck should also be cleaned using wash port after each use, as grass clippings, leaves, dirt,
and other debris will accumulate, especially when grass is wet or has high moisture content. This accumulation is
undesirable, as it will harden, restricting blade and air movement, probably resulting in a poorer quality of cut and even
promoting rust and corrosion.
Using wash port to clean mower deck
NOTICE: Follow this procedure after EACH USE to prevent buildup
and remove corrosive lawn chemicals.
IMPORTANT: You can wash the machine with a mild detergent and
water. Do not pressure wash the machine. Avoid excessive use of
water, especially near the control panel, under the seat, around the
motors and all electric components and bearings.
1. Set the parking-brake pedal to the braking position. Refer to
section "SETTING THE PARKING BRAKE" in this manual.
2. Adjust the mower deck height to the lowest. Refer to section "ADJUSTING THE CUTTING-DECK HEIGHT" in this
manual.
3. Attach the supplied wash-port quick-coupler to garden hose.
4. Attach garden hose with quick-coupler to the wash port on the mower deck as shown in Fig. 22 until you hear a
clear click. The wash port is on the left side of the mower deck.
5. Turn on the water.
6. With battery packs attached, insert the safety key, and press the start/stop button for 3 seconds to illuminate the
LCD screen.
