GMX –INSTRUCTIONS FOR USE
** New battery may be partially charged, fully charge before use
** Ensure spray switch connected inside control box (see maint-page 2)
1) Ensure power turned off on both pump isolator switch (on control panel) and
spray switch (on handle bar).
2) Unplug and remove 2 x connectors (top of paint tank). Remove paint tank (using
front and rear recesses) by lifting out back first, then the front.
3) Make up paint mix (using paint concentrate and water) –using only BOWCOM
paints. Pour into tank through integral basket filter.
4) Replace paint tank lid and place onto GMX machine, re-connecting both plug-in
connectors (ensure matching sides-colour coded).
5) When closing bonnet with connectors attached to tank, carefully push surplus
hose down back of tank to avoid restricting bonnet closure.
6) Fill cleaning bottle with tap water (located on top of control panel).
7) Ensure direction tap is set to Paint and recycle tap is set to spray.
8) The machine is now ready to mark a line.
9) Set the spray limit plates to the required line width. Ensure that the spray gun is
set high enough for the paint spray to hit the limit plates.
NB. To locate the spray head inside the frame –use the right-hand stub
(from behind machine)
To locate the spray-head outside the frame –use the left-hand stub
(from behind machine)
NB. For offset (left or right side) spray marking –use the extended spray bar
(optional extra).
10) Turn on the pump isolator switch (located on control panel) –observe the volt
meter reading (12 volts). If too low, place battery on charge.*
11) To activate pump, use the button located on the handle bar. This can be used in
the locked-on position or Hold-position (using a light finger touch).
NB. The push button spray switch is positioned on the right side of the handle,
this can be moved to the left side if required.
12) To clean the machine: Turn off pump. Turn the paint/water tap to water (located
next to the water bottle inside control box).

13) Turn on paint spray switch (as when spraying paint) and water will appear at the
nozzle. On sight of water, turn off. Also spray water whilst on the re-cycle mode
(to clean re-cycle pipes). Remove and clean top-hat filter –inside spray head
above the nozzle.
NB. A full water bottle should equal approx. 3 x cleans.
14) Should paint be left in the paint tank overnight, it can be agitated by using the
recycle option on the tap inside the control box (to the right of the pump). Turn
pump on as normal and the paint will re-circulate back into the tank. Turn off
when fully re-mixed.
15) NB. For ease & weight of transporting the GMX, remove paint tank (if full). When
disconnected, always place the tank connectors into the slots provided on
underside of bonnet.
* NB. Battery Charger Use Battery Charger provided. Place 3-pin plug into 240 volt
mains socket. Plug other end (12 volt) into socket on side of
Control Box. A full charge will take up to 10 hours. Full
battery should operate pump for several days (dependent
on use).
** NB. Handle & Switch Handle height can be adjusted for comfort of user and can
also be removed for ease of transportation.
NB. For handle removal, disconnect 2 x bullet connectors
inside control box (terminals are both common & not sided)
MAINTENANCE
1) During prolonged periods of non-use, the paint tank should be washed out
manually and drained (using black rubber plug on rear of tank). Also clean the
basket filter (in top of tank) and the paint filter (on end of paint suction tube)
2) Remove all 3 x plug-in connectors (2 on tank, 1 on spray hose coil) and lubricate
with WD40 on a daily basis.
NB. When not in use, leave the 2 x tank connectors disconnected & clipped to the
underside of the bonnet.
3) During prolonged periods of non-use, disconnect the spray hose coil.
4) Keep control box interior free of water & paint. Remove any surplus / spillage by
using small black rubber plug on the base of the control box.
