Step 3. Recharge the Mower Before First Use You MUST recharge the battery pack before the first use of the machine, or the battery pack may suffer permanent damage. Read the section "Initial Charging" on page 6 of this manual before you operate the mower. Step 4. Read these Safety & Operating Instructions Before Using the Mower. Anyone operating the DR® WHISPER LITE® CORDLESS Electric Mower should be thoroughly familiar with these instructions.
Battery Care & Charging Before charging the battery pack, read all instructions and cautionary markings in this manual and on your mower. Do not operate your mower until you have read and understand all instructions and the battery pack has been fully charged. Battery Pack The battery pack in your DR® WHISPER LITE® CORDLESS Electric Mower is composed of two completely sealed 12V lead acid batteries inside a pack connected serially to a 24V motor.
Initial Charging IMPORTANT! The battery pack in your mower has been charged at the factory. However, you must recharge the battery pack and make sure it is fully charged before initial operation of the mower. Failure to do so may cause permanent damage to the battery pack. ! WARNING: Make sure the electrical power supply is normal household voltage (110 volts). Plug the charger directly into an electrical outlet. Do not abuse the cords. Never carry the charger by the cord.
2. Charging with the Battery Pack Removed from the Mower · Remove the battery pack from the mower to recharge (Figure 5). Connect the charger plug to the charger receptacle on the battery pack (Figure 6), then plug the charger into a wall outlet. A red light on the battery pack will indicate the battery pack is being charged. Note: The red light on the battery pack only indicates that the charger is plugged in and the battery is charging—it will not automatically turn off when charging is complete.
Recharging After Each Use of the Mower IMPORTANT! Always recharge the mower to a full charge immediately after each use, no matter how short a time it was used, even if the battery power indicator on the control panel is still green. This is important in order to maintain maximum mower performance and extend maximum battery pack life. If the mower is stored with a depleted battery pack, the batteries will become permanently damaged within a short time. Recharging to a Full Charge for Off-Season Storage 1.
Controls & Features Make yourself, and all other operators, familiar with the controls, parts and operation of the DR® WHISPER LITE® CORDLESS Electric Mower before using it.
Key Hole/Charger Receptacle The key hole is the receptacle for both the external battery charger and the safety key, which is inserted to run the motor. The key hole is designed so that you can never connect the external battery charger and insert the safety key at the same time (Figures7 & 8). Safety Key The safety key must be inserted to run the motor. The safety key has a built-in circuit breaker to protect the motor.
Operating Instructions Pre-Start Checks If the mower battery pack is not fully charged, or if you are unpacking a new mower for the first time, read the section on Battery Care & Charging on page 5 before operating the mower. ! WARNING! Do not insert the safety key until all pre-start checks have been made and you have moved to the mowing area. Þ Check under the mower deck and make sure you are using the correct blade (for mulching or grass collection), and that the blade is attached properly.
4. Continue to hold the operator presence control bar against the handlebar for as long as you want the motor to run. Note: Releasing the operator presence control bar will immediately switch off the motor and the blade will stop spinning within three seconds. ! WARNING! The operator presence control bar is a safety device. Do not tamper with it. To Stop the Motor and the Blade 1. To stop the motor and the blade simply release the operator presence control bar (page 9, Figure 7).
The handle may be placed in one of six cutting height positions: Lever Position Cutting Height 1 1" (Lever Highest) 2 1-1/4" 3 1-4/5" 4 2-1/4" 5 2-3/5" 6 3" (Lever Lowest) 1. Remove the safety key. 2. Make sure all four wheels are level. 3. The height adjustment lever is spring loaded. Squeeze the lever outward (toward the wheel) and out of its position notch. 4. Move the lever to the desired notch.
Using the Optional Grass Catcher To Attach the Grass Catcher 1. Raise the hinged discharge guard on the rear of the mower. If the optional plastic discharge chute block is installed, pull it out by its handle. (The block is seated in the chute by "press fit" and it may be necessary to pull quite hard.) 2. While keeping the discharge guard raised, insert the grass catcher into the holes on both sides of the mower (Figure 12). 3.
Mowing & Lawn Care Tips · For best results, mow at a steady pace. If you try to walk too quickly, especially in tall grass, the quality of the cut may not be uniform. · Mow as often as needed so that you are only cutting 1-2" of grass each mowing session. Trying to cut more than 2" will drastically reduce the charge life of the battery pack. · For the healthiest lawn, avoid removing more than one third of the leaf blade during any one mowing session.
Maintenance Cleaning Supplies Needed: • clean, damp cloth or sponge • mild soap or detergent (if needed) • soft nylon brush (if needed) ! WARNING: ALWAYS remove the safety key before performing any adjustments, maintenance or repairs. 1. Remove the safety key. 2. Use a damp cloth or sponge, with a mild soap or detergent if necessary, to clean the mower. Do not use water or solvents for cleaning. Remove any clippings that have accumulated on the underside of the deck and in the discharge chute.
4. Loosen the blade nut (Figure 16) with the socket or adjustable wrench. The blade nut turns counterclockwise to loosen. Hold the steel hex adapter steady in one hand to prevent the motor shaft from turning, while loosening the blade nut with the other hand. 5. Remove the blade nut, steel hex adapter, blade, plastic spacer and steel blade adapter (Figure 16). To replace a sharpened blade or to install a new blade, reverse steps 1 – 4 above.
To Sharpen the Blade on the Mower 1. Remove the safety key. 2. Turn the mower over on its right side (when in the operating position) to expose the blade. 3. Wear safety glasses. Hold the blade and carefully file the cutting edges using even strokes. File both sides of the blade equally. To Balance the Blade Because you are removing metal from each side of the blade, make sure to remove an equal amount from each side to keep the blade balanced.
Storage Whether you store the mower for a short or long time, always remember these important guidelines: · Always store the mower with a full battery charge and follow the recharging instructions in the Battery Care & Charging section. · Always store the mower in an environment where the temperature is between –4°F (–20°C) and +104°F (+40°C). Make sure the storage temperatures will never be outside these limits.
Troubleshooting ! WARNING: ALWAYS remove the safety key before performing any adjustments, maintenance or repairs. Problem Corrective Action Motor fails to start when safety key is inserted, button and operator control bar are depressed Þ Check to make sure the safety key is properly inserted. Þ The blade may be obstructed. Remove the safety key, turn the mower over and check the blade. Þ Is the battery pack fully charged? Plug in the charger and check the lights.
Mower is hard to push Þ Mower is trying to cut too much grass. Raise the cutting height. Þ The wheels may not be rotating freely. Remove the safety key, turn the mower over and check the wheels for damage. Battery pack looses its charge quickly Þ Was the battery pack fully charged when you began? Charge the battery pack if necessary. Þ The grass may be too high or too thick. Try adjusting the cutting height higher, and/or mowing a narrower swath.
