ASSEMBLE THE HANDLE SECTIONS  
1. Set the cutting height to the highest setting as shown below. This  
will make it easier to attach the lower handle section.  
a. Loosen the two large black knobs [Part # 9], one on each side  
of the mower body, to allow movement of the height  
adjustment arms [Part # 11]. NOTE: the handle is mounted to  
the adjusting arms and thus moves with the arms.  
b. Set the height to the highest setting and re-tighten the black  
knobs.  
2. Fit the lower section of the handle [Part # 4] so that the holes are  
over the handle posts on the mower. [See Insert B] Then rock the  
handle to align the locking tabs and allow the handle section to fit into  
place. Place the spacer [Part # 7] over the post and put the cotter pin  
(Part # 8] through the hole to secure the handle.  
3. Continue assembly of the middle [Part # 3] and top sections [Part  
# 1] of the handle using the handle bolts and wing nuts [Part # 5 and  
6].  
ADJUSTING THE CUTTING HEIGHT  
The cutting height of the MM-2 may be adjusted from approximately  
1.0 inch up to approximately 2.9 inches. Actual height may vary  
according to the height of the turf. Adjust the mower to the desired  
height as follows:

Owner’s Manual — Sunlawn MM--2  
1. Loosen the two large black knobs [Part # 9], one on each side of  
the mower body, to allow movement of the height adjustment arms  
[Part # 11]. (This is the same movement used to attach the  
handle.) NOTE: the handle is mounted to the height adjustment  
arms and thus moves with the arms.  
2. Set the height, using the scale on the back of the adjusting arms to  
the same setting on both sides and re-tighten the black knobs. The  
mower is now ready to mow at the desired height setting.  
OPERATION  
INSPECT THE MOWING AREA  
1. Before beginning to mow, remove any foreign objects, such as  
stones, branches, or toys, from the area.  
2. Continue to check for such obstacles during mowing.  
The Lawn Should Be Relatively Dry

Owner’s Manual — Sunlawn MM-2  
1. Mowing wet grass causes an uneven cut and can cause damage to  
the electrical components of the mower.  
2. Do not mow when it is raining.  
!
WARNING  
Before starting the mower, check within the blade area for any  
foreign objects and remove them.  
Do not operate the mower on areas other than turf surfaces.  
The mower should be sitting upright on a level part of the lawn  
before starting operation  
NORMAL MOWING  
To obtain a clean cut, push the mower in straight lines (passes) at a  
deliberate walking pace. Overlap the passes to even the cut and to  
avoid any uncut strips.  
MOWING USING THE GRASS CATCHER (OPTIONAL ACCESSORY)  
The grass catcher collects the clippings as it mows.  
1. Install the catcher apron [Part # 14] on the non-spring pin side  
2. Push the spring pin on the other side  
3. Install the apron on the spring pin side  
The grass catcher attaches at the grass catcher hooks on the mower  
and by the strap to the mower handle, as seen below.

Mow using the same procedure as for normal mowing (described  
above).  
MOWING: GENERAL INFORMATION  
THE 1/3 RULE  
This is the key to enjoyable mowing and a healthy lawn.  
1. The lawn should be mowed regularly, at least once a week during  
the growing season.  
2. Be guided by observing the lawn and taking care not to remove  
more than 1/3 of the total height of the turf at any mowing.  
3. Following this rule will stimulate the turf’s root growth, maintain its  
health, and encourage its natural ability to crowd out unwanted  
weeds.  
If the lawn has become too high (over 4 inches in height) then it is  
best to set the mower to the highest setting to mow. After mowing,  
reset down to the normal level and mow again within a day or two.  
Removing too much of the turf’s height, especially in the heat of  
summer, can cause root shock and weaken the lawn; bringing down  
the height by successive mowings over two or more days can avoid  
this damage and maintain the health of the turf.

Owner’s Manual — Sunlawn MM-2  
If the lawn is overgrown (to higher than 4 inches) it may be advisable  
to use a brush cutter to remove the excess turf mass before resuming  
mowing at normal heights.  
MAINTENANCE  
CLEANING  
After using the mower, clean with a moist cloth. Spray the cylinder  
and cutting bar with silicon spray lube.  
GENERAL MAINTENANCE  
Regularly check to insure that all bolts, nuts, and screws are tight and  
that the mower is in good working order. Worn out and damaged parts  
should be replaced.  
The blades, if properly cared for, will mow for years before requiring  
sharpening. Sharpening can only be done by a professional using  
a cylinder grinder and proper techniques.  
STORAGE  
1. Store the MM-2 in a cool, dry place.  
2. The mower should be stored out of the reach of children.  
READJUSTING THE BLADE CLEARANCE  
The blades are optimally adjusted from the factory. However, after  
using the mower for a long period, if the cut is not clean, the blades  
need readjusting. The procedure is as follows:  
1. Turn the mower over to expose the cutting bar on the bottom of the  
mower. [Part # 17].  
Using a 10mm open end wrench, tighten the hex bolt approximately  
1/4 turn [Part # 19] at one end of the cutting bar until the cutting bar  
and cylinder come into contact. Spin the blade cylinder by hand and  
back off the bolt approximately 1/8 turn or until the cutting bar and  
cylinder are no longer in contact.

2. Make the same adjustment at the other end of the cutting bar.  
3. Now check the adjustment using the small 0.05mm/0.002 inch  
gauge (silver strip) supplied with the MM-2 (or any 0.05mm/0.002  
inch feeler gauge). If the gauge is held by the cylinder blades but  
the cylinder and cutting bar are not touching then the adjustment is  
correct.  
4. The blades may also be tested by inserting a piece of paper  
vertically into the blades while turning them by hand.  
!
WARNING  
Blades are sharp! Be careful of injury —  
handle the blades carefully to avoid  
cutting yourself. Wear appropriate gloves  
or hand protection.
