The mover has two Motor Units (1 & 2). In general they are mounted in front of the axle of the caravan/trailer. Both units
are identical but cannot be switched. Please refer to Fig.2 for Model No: EM4445 and Fig.4 for Model No: EGO200

Always ensure that you are close enough to engage the caravan’s handbrake when manoeuvring on
uneven terrain and gradients/slopes in case of mechanical failure. Do not use the mover as a brake,
when you have finished manoeuvring always engage the caravan’s handbrake.
SAFETY FIRST! Ensure that there are no persons or obstructions in the vicinity of the caravan prior to
testing.
In order to engage the rollers, fit the end socket of the Engagement Tool (6) on the spindle (Fig.2G & Fig.11A) on the right
or left drive unit.
Position the engagement tool parallel to the ground, then rotate the tool through approximately 180° degrees.
Note: to engage the rollers you always rotate the tool towards the tyre, irrespective of which side you are operating the
engagement from.
The engagement mechanism utilises a simple over-centre cam that pushes the rollers onto the tyres and then locks into
place automatically. If the mover has been installed correctly, at exactly 20mm away from the tyres when disengaged,
the amount of force provided onto the tyre by the roller will be sufficient for most circumstances of use (Fig.13).
To disengage the rollers, simply refit the tool onto one of the spindles and rotate away from the tyre. Please note that you
will feel a small amount of resistance initially as you disengage the cam from its locked position; the spring will then do
the rest of the work and pull the roller away from the tyre and into the fully disengaged position (Fig.12).
To engage the rollers onto the caravan’s tyres use either an appropriate power drill with the included Engagement Drill
Adapter (34) or the included Universal joint Adapter (33) and the caravan’s corner steady tool.
Fit the engagement tool onto the Engagement Spindle (refer to Fig.7A) on either side of the mover. Depending on which
side you are connected, you need to turn the spindle clockwise or anti-clockwise so that the roller moves towards the
caravan’s wheels (refer to Fig.8 + Fig.10).
There is an indicator (Refer to Fig.9) on the side of each motor unit which has two vertical lines. The marker on the plas-
tic side cover needs to point within the two lines, which should provide adequate grip and traction for most situations of
use.
Once the marker points within the two line zone, you can release the caravan’s handbrake.
Under some circumstances, such as difficult terrain, it is acceptable to engage the rollers further onto
the tyre, which will make the marker point beyond the two line zone. However, if the marker points
beyond the two line zone when operating in normal, undemanding terrain, please refer to the
troubleshooting section.
Do not over-engage the rollers – this could cause undue stress on the unit and could result in personal
injury.
