Operation; Maintenance - Honda UMS425E Owner's Manual

NOTE: Should you have difficulties to re-start a hot engine, follows
this procedure:
1. Turn the engine to the OFF position (O).
2. Make sure that the choke lever is in OPEN position.
3. Keep the throttle control lever (throttle trigger) fully squeezed.
4. Pull the starter grip 3 to 5 times, and release the throttle control
lever (throttle trigger).
5. Start the engine referring to the procédures described above.
CAUTION: CAUTION:
• Be sure to turn the engine switch to the OFF position (O).
• If this operation is executed with the engine switch at the ON position,
the flexible cutting means may rotate when the engine starts and a
personal injury may result.
STOPPING THE ENGINE
1. To stop the engine, press the
Start/Stop button to engage
the Stop position [1].
2. This step can also be taken to
stop the machine in case of
emergency.
Note that the cutting attachment
continues turning by inertia after
the engine has been stopped.

OPERATION

OPERATING POSITION
When handling the machine, take care to avoid striking any
objects with the cutting attachment and keep the cutting
attachment away from your body.
Hold the grass trimmer firmly by both grips as shown [3].
CAUTION: CAUTION:
• When using the machine, always
allow the engine to idle between
operations. If the machine is
allowed to run at maximum speed
with no load (no resistance on the
cutting attachment) for long
periods, the engine may be
seriously damaged.
This attachment is designed to
complete the job done with a
lawnmower. It is especially handy
and efficient for cutting grass along
walls or fences, around trees or
posts and on narrow or uneven
surfaces where a lawnmower
cannot be used.
Make sure the line cutting blade [4] is properly mounted on the
cutting attachment guard.
LINE LENGTH ADJUSTMENT
At maximum rotating speed,
gently press the flexible cutting
means on the ground. The line is
automatically extended. Repeat
this operation until the optimal
length is obtained.

CUTTING
The nylon line cuts grass cleanly without damaging tree bark and
avoiding the violent impacts that would occur between a rigid cutting
attachment and hard surfaces.
It is, however, recommended not to work too long in such areas in
order to avoid damaging fragile, immature plant, in particular, and to
avoid premature line wear.
Proceed in stages, when trimming, tilting the cutting attachment slightly.
For larger areas, hold the cutting attachment horizontal and sway it
sideways from right to left and from left to right, alternately.
CAUTION: CAUTION:
• Do not rest the bottom of the cutting attachment on the ground as this
could damage it, as well as your lawn.

MAINTENANCE

ENGINE OIL CHANGE
NOTE: Drain the oil while the engine
is still warm to assure rapid and
complete draining.
1. Check the fuel tank cap [6] is
tightened.
2. Remove the oil filler cap [5] and
drain the oil into the oil
container by tipping the engine
toward the oil [7] filler neck.
3. Refill with the recommended
and check the oil level [8]
