Melnor 4500 - Manuel

A lush beautiful lawn is the pride of any homeowner. Your
Lawn Rescue Traveling Sprinkler will help you keep your grass
growing green all season long. The unique design allows you
to water your entire lawn, up to 15,000 square feet, without
moving the sprinkler. The Lawn Rescue Traveling Sprinkler
moves itself.
Assembly
The Lawn Rescue Traveling Sprinkler comes nearly fully
assembled. All you need to
do is attach the spray arms.
No tools are required.
Simply insert each spray arm
into the “T” shaped tube on
top of the sprinkler. Secure the spray arm with the plastic nut
that is already on the spray tube. Note the position and angle
of each spray arm in Figures
A and B. For correct operation,
the spray arms must be positioned as shown. To change the
position of the spray arm you may need to loosen the nut just
a bit, reposition the arm, and then retighten the nut. Be careful
not to overtighten the nut.
Set-up
The Lawn Rescue Traveling Sprinkler follows the course of the
hose as it moves around your lawn. The unit will travel from the
far end of the hose back toward the spigot.
Arrange the hose across the lawn to create the path you want
the sprinkler to follow. Be careful not to make the curves too
sharp. The sprinkler should go up and down gently sloping hills
without any problem (15° maximum incline).
Place the sprinkler’s guide wheel over the hose, heading in
the direction of the spigot. The hose should run between the
two large rear wheels. Make certain there is at least 6 feet of
hose extending beyond the sprinkler. Now, attach the hose to
the sprinkler.
Determine where along the course of the hose you want the
sprinkler to end its run. Place the included Water Stop over the
hose as shown in figure
C. Two water stops are included. The
longer one is for soft soil. The shorter one is for hard soil. When
the sprinkler reaches this point in the hose, the valve will close
and watering will stop.
NOTE: There is still water pressure in
the hose. Turn the water off at the spigot before detaching
the hose.
Operation
The Lawn Rescue Traveling
Sprinkler has three speeds
— Fast, Slow and Neutral.
Select the desired speed.
Neutral provides stationary
sprinkling. Slow spreads
the maximum amount of water over the watering area. Fast
spreads less water over the same area.
With average water pressure (60 psi), the Lawn Rescue
Traveling Sprinkler should move about 90 feet per hour on the
fast setting and 45 feet per hour on the slow setting.
Once you have selected the speed, simply turn on the water
at the spigot. Water will begin spraying and the sprinkler will
initiate its movement around your lawn. Once the sprinkler
reaches the Shut Off, the Lawn Rescue Traveling Sprinkler will
simply stop.
Storage
Disconnect hose and drain all water from the sprinkler before
storing. Water freezing inside the unit will cause damage.
Turn the speed selector to Neutral.
You may want to remove the spray arms to avoid accidental
damage.
For best results, use a 5/8”
reinforced hose. Maximum
hose length: 200’.
When using the unit as
a stationary sprinkler or
moving the sprinkler, turn the
speed selector to “Neutral”.
