5. OPERATING INSTRUCTIONS
5.1 Before Starting
5.1.1 Read this Handbook carefully.
5.1.2 Level the unit and jack or chock to prevent
movement in use.
5.1.3 Check the engine fuel and lubricating oil
levels. Top up as necessary.
5.1.4 Check the mechanical seal oil level using
the dipstick fitted to the filler plug.
5.1.5 Check the vacuum pump drive belt is
correctly tensioned.
5.1.6 Starting:- Ensure that the battery is charged
and ready for use.
5.1.7 Check that air inlets are unobstructed and
that the cylinder vanes are free from debris.
5.1.8 Check that the discharge non-return valve
is seating properly and that there is no
debris in the ball chamber that may prevent
correct operation.
5.1.9 Select and fit a suitable strainer for the job
in hand. Note that most ‘off the shelf’
strainers are for general purpose use. As
such they may not protect the pump against
oversize solids. For applications where
stones, etc., may be drawn in, then a
strainer with holes slightly smaller than the
pump handling capacity must be employed.
Refer to the Technical Data section for
details.
5.1.10 Connect suction and delivery hoses making
sure that there are no sharp bends in the
lines. Where the hoses pass over sharp
edges or abrasive surfaces ensure that they
are protected by suitable means to prevent
chafing. Ensure that the suction hose end
is fully submerged.
5.1.11 Check that the surge control valve is fully
screwed in. This is the large indented nut
surrounding the surge control valve knob on
the top of the priming tank.
5.2 Starting
5.2.1 Read the manufacturer’s instructions for the
Hatz engine in conjunction with the
following:
5.2.2 Push the decompressor lever(s) to the ‘Run’
position.
5.2.3 Turn the keyswitch to the ‘Start’ position
5.2.4 Release the keyswitch once the engine has
fired and got away.
5.3 After Starting
5.3.1 The pump will prime automatically once the
suction hose is submerged. If the pump
fails to prime refer to the fault finding guide.
(Section 8)
5.3.2 If the pump continually snores, gradually
release the surge control valve until the
vibrations reduce.
5.4 Stopping
5.4.1 Read the manufacturer’s instructions for the
Hatz engine in conjunction with the
following:-
5.4.2 Turn the keyswitch to the ‘Off’ position.
5.4.3 Open the volute cock to drain the volute.
Close after draining is complete. This must
be done before removing the suction and
delivery hoses.
5.4.4 When you take the pipes off there is a
chance that there will still be water in the
pipes so caution is advised.
