Congratulations on your purchase of this new Simplicity mower. As you use it, you will find that it has been engineered with imagination and built with integrity.
To take advantage of all of the fine features built into this machine for your benefit, read and study this instruction booklet thoroughly before operating the mower. The few minutes you spend studying it will repay you many times over in the time you save in mowing and the pleasure you experience in using it properly and safely.
Should warranty service be necessary, the information below should be presented to the authorized SIMPLICITY Dealer.

Simplicity mowers are completely assembled at the factory, but certain adjustments are necessary to suit your particular needs. CAUTION: Never make any adjustments (except engine speed) with the engine running. Check to make sure the speed control is in the off position before making adjustments.
To unfold the handle, loosen the two wing nuts, Fig. 1, all the way against the retaining nuts. Stand on the left side of the mower and place your foot just behind the left rear wheel. Grasp the black vinyl covered section of the handle, pull it up and back until it snaps into place. Tighten the two wing nuts with firm hand pressure.
Figure 1
Figure 3
See Fig. 4. Lift the front end of the two handle locks and rotate the handle fully forward. The Handle will remain in this position until pulled back, when locks will automatically engage.
The handle height (in operating position) may be varied to suit different heights of operators. The mower is shipped with the handle in the low position which is most comfortable for persons 5'-8" or less in height.
Remember, for tall operators use the upper holes and for shorter operators, use the lower holes. See Fig. 5.
Figure 5
Most lawns should be mowed between 11/2" and 2" high. It is desireable to leave the grass higher when dry conditions exist. Never remove more than 1/3 of the height of the grass or a maximum of 1" in one mowing if you want the lawn to remain green.
For mowing extremely tall grass, set the cutting height at maximum for the first mowing and then reset to the desired height and mow again.
There are 6 positions of cutting height adjustment from 7/8" to 2-7/8". Each notch changes the height by about 3/8". The mower is shipped with all adjusters in the shortest cut position.
CAUTION: Never change height adjustment with the engine running. Make certain that the speed control is in STOP position.
To increase cutting height see Fig. 4.
If the clippings are to remain on the lawn mow with the If the clippings are to remain on the lawn, mow with the discharge chute dispersing the clippings toward the cut portion
If clinnings are to be raked up later and the grass is at normal height of 3" or less, it is practical to disperse the clippings into the uncut portion. They will all be concentrated in the center of the lawn for minimum raking.
The mowing pattern while catching the clippings can be varied to suit the lawn arrangement. Best lawn appearance will result if the direction of mowing is alternated each mowing and a diagonal mowing pattern is used every 4th time.
Please read the engine manual and understand it thoroughly before using the mower.
The automatic choke automatically provides the proper mixture for starting with outside temperatures from 30° F. to 100° F., the first start of the day or just after shut down. If the engine fails to start after 5 pulls or 5 seconds of electric starter cranking, it may be flooded.
Flooding may occur if the mower is tipped to one side.
To clear a flooded engine, rotate the speed control, Fig. 2, to the stop position. This blocks the choke open. Pull the starter 6 times or crank electrically for 6 seconds. Set the control at start and follow the steps under starting listed above.
The engine speed may be set anywhere in the mow range for most mowing.
The lowest speed (toward stop) of the mow range is satisfactory for most grasses of normal height. Operating at this speed reduces noise and fuel consumption and is recommended for average conditions.
Very light wispy grasses such as bahaia and ryc may require full engine speed for clean cutting. Very heavy or tall grasses should also be cut at higher engine speeds.
If the grass is damp, the bag will fill better at higher engine speed.
Manual start engines should be stopped by rotating the speed control counter-clockwise to the stop position. See Fig. 2.
Electric start models should be stopped by rotating the key, see Fig. 9. counter-clockwise to the stop position. Leave the engine speed control at your favorite mowing speed. CAUTION: Always remove the key from electric start machines when leaving them unattended.
The over-the-ground speed with the touch-o-matic control fully engaged and the engine speed control fully clockwise is 2.75 miles per hour. With the engine speed control at the low end of the mow range, it is 2.15 miles per hour.
Over-the-ground speed can be reduced for any engine speed by applying less pressure to the touch-o-matic control bar and permitting the drive rollers to slip on the tires. The mower is designed to operate under these conditions. The touch-o-matic control bar can also be pushed all of the way forward to an "over-center" position to reduce effort on long stretches. You then merely guide the mower and pull back on the control bar to stop forward travel.
To turn, pull the touch-o-matic control bar all the way back. This disengages the rollersfrom the wheels and permits them to turn freely for pivoting the mower. Raise the front wheels just above the ground by applying downward pressure on the control bar and pivot the mower. When the turn is complete, release the downward pressure and push the control bar forward. The mower will smoothly come to speed.
Walk over the entire area to be mowed, and remove any foreign objects.
2. Move all people and pets from around the mowing area and keep them away until mowing is finished.
To keep your Simplicity mower operating at peak efficiency follow these simple steps.
Deep nicks in the blade cutting edge can only be corrected by grinding which requires that the blade be removed and balanced. See Your Simplicity Dealer for this service.
CAUTION: If you feel severe vibration, the blade is unbalanced. See your Simplicity Dealer and have the blade balanced before using the mower.
A properly adjusted touch-o-matic drive will spin the wheels on dry pavement with the control bar fully forward and the operator holding back on the handle. If the rollers slip on the tires rather than the tires slipping on the pavement, the touch-o-matic drive requires adjustment.
Note: If the rollers don't turn, the belt is slipping usually because it is wet. If this occurs, running the drive a few minutes will dry out the belt.
To correct the roller slipping on the tire, procede as follows: 1. Determine which roller is slipping
Do not attempt to remove the blade unless you have box, socket, or open-end wrenches which fit the bolts. If you have such equipment procede as follows:

The nickel Cadmium battery requires no water and may be placed in any position. The only maintenance required is charging, which should be done as follows:
CÁUTION: Do not charge the battery at temperature below 40o F, and use only the charger furnished with the mower, or the battery will be damaged.
1. Charge battery for 24 hours before using the starter.
2. The charger may be left on continuously without damaging the battery.
If it is more convenient to remove the battery for charging or the temperature is below 40° F, proceede as follows: Battery Removal from Mower
