Pre-Operation For Starting - Makita EW120R Instructions For Use Manual

3. PRE-OPERATION FOR STARTING

(See Fig. 2 2 2 2 2 )
1. CONNECT SUCTION HOSE
(See Fig. 2 2 2 2 2 -q q q q q )
Use a reinforced-wall or wire braided hose to prevent suction
collapse.
Since the pump self-priming time is directly proportional to
hose length, a short hose is recommended.
Always use a strainer with the suction hose. Gravel
or debris sucked into the pump will cause serious
EN
damage to the impeller and the pump casting.
2. CONNECT DELIVERY HOSE
(See Fig. 2 2 2 2 2 -w w w w w )
When using a fabric hose, always use a hose band to prevent
the hose from disconnecting under high pressure.
3. CHECK ENGINE OIL (See Fig. 2 2 2 2 2 -r r r r r )
Before checking or refilling engine oil, be sure the engine is
located on stable, level surface and stopped.
Do not screw the oil gauge into the oil filler neck to check
■
oil level. If the oil level is low, refill to the upper level with
the following recommended oil.
Use 4-stroke automotive detergent oil of API service class
■
SE or higher grade (SG, SH or SJ is recommended).
Select the viscosity based on the air temperature at the
■
time of operation as shown in the table. (See Fig.2-e)

q Maximum Fuel level
Do not fill above the top of the fuel filter screen (marked q),
■
or the fuel may overflow when it heats up later and expands.
(Except EW120R)
Reattach the fuel cap by turning clockwise until reaching
■
the physical stop (about one quarter turn). Do not attempt
to turn past the physical stop or the fuel cap may be
damaged. (Except EW120R)
■ When filling the fuel tank, always use the fuel filter screen.
Wipe off any spilled fuel before starting the engine.

5. CHECK PRIMING WATER
(See Fig. 2 2 2 2 2 -u u u u u )
It is recommended that the water chamber of pump casing
should be primed with full of water before operating.
WARNING
Never attempt to operate the pump without priming
water or the pump will overheat. Extended dry
operation will destroy the mechanical seal.
If the unit has been operated dry, stop the engine
immediately and allow the pump to cool before
adding priming water.
