INTR DU TI N This operator's manual is intended to provide the information necessary for operating and maintaining your lawn mower. Its primary purpose is to offer you guidance in the lubrication and adjustment of your lawn mower during daily and seasonal operation.

We especially wish to call your attention to the many safety advisories listed in this manual. Although your lawn mower is designed with safety of operation in mind, the risk of accidents cannot be completely eliminated unless you understand and practice all safety precautions.

Timely service saves costly repairs and valuable time lost because of breakdowns. When it becomes necessary to make repairs or replacements to your lawn mower, be sure to insist on genuine ISEKI parts. These parts are designed specially for your rotary mower under controlled specifications, to provide satisfaction and the long lasting service to which you are entitled. Your dealer can supply you with the parts you require. Use of other than genuine ISEKI parts may jeopardize our normal warranty. For additional information consult your dealer.

By the way, we want you to understand that the contents of this manual may be somewhat different from the standards pertaining to the machine that you actually own. This is because we are always aiming to improve our technical and qualitative standards, and are very quick to introduce improvements into our machines.

There are some paragraphs italicized to call your attention in this manual. They are classified into the three groups mentioned below.

lever

Grasp the lever, and the blade starts rotating.

TYPE E:

• When the lever is grasped, the mover starts travelling but the cutter does not turn (Type B).

Consequently, the mower can move self-propelled to another place without mowing.

• Mowing is started by grasping the travel-clutch lever as the cutter is turning while the engine is in operation.

Note: In ordinary operation, the travel-clutch lever should be operated only when the engine speed has risen sufficiently after engaging the cutter-clutch. e

On the grass which has grown too tall, the engine may stall when the lever is grasped. In such a case, lift up the mower deck front by pushing down the handle bar when operating the lever. The clutch will then engage smoothly.

Caution: Operate the level'quickly. Slow operation ofthe lever causes a half-engaged condition of the clutch, which will lead to abnormal wear andfinal seizure ofthe clutch. (Type B) C.

Travel-clutch lever (except fortype P) The mower starts travelling when the lever is grasped and stops when the leveris released.

Too quick mowing start will cause engine stall and uneven mowing. (Type B)

5. MOWING TYPE B: • First, grasp the blade-brakeclutch lever and wait until the engine speed has risen sufficiently. Then engage the travelclutch to start mowing.

As the travel-clutch lever is interconnected with the cutterclutch lever, mowing operation can be continued by holding the travel-clutch lever alone.

• When the travel-clutch lever is released, the blade-brake-clutch lever is also released. Independent operation of these levers is also possible.

-13-

Caution: The mower stops travelling when the travel-clutch lever is released, but the cuttergoes on turning. Consequently, be sure to stop the engine before removing the collector or opening the discharge-cover.

o MOWING PUSHED BY HAND • When mowing under trees or beside walls, operate the mower only with the cutter-clutch engaged and push it by hand without engaging the travel-clutch.

(Type B) • As the cutter is turning while the engine is in operation, push the mower without manipulatingthe travel-clutchlever. (Type E)

6. REMOVAL AND INSTALLATION OF THE COLLECTOR Caution: Push the mower slowly and carefully paying attention to the positin ofyour feet. Never run while pushing the mower to avoid injury.
