Assembly Instructions
Tiller assembly
To t the tiller assembly, you will require the hand-
knob and spring. Fit the hand-knob through
the right-side hinge and locate the spring over
the shaft of the bolt. Align both hinge joints and
locate the thread of the hand-knob into the right
side of the hinge. Adjust the tiller to the desired
angle and tighten the hand-knob fully.
There are two electrical connections - with white
and black plugs. These should be connected to
the matching colour connector. When connected
carefully push the connectors one at a time
through the hole in the chassis cover and t the
grommet (a small amount of washing up liquid
rubbed on the grommet can make it easier to
locate).
Note:
Before using your scooter the tiller and seat post will require tting.
Seat post assembly
To t the seat post the rear part of the scooter will
need to be removed (see page 14) to access the
securing bolt.
Locate the seat post and align the holes in
the frame and the post at the desired height.
Tighten the bolt using the allen key and spanner
provided. Re-t the rear part of the scooter.
Scooter fuse assembly
To t the seat post the rear part of the scooter

The scooters speed and direction is controlled by the ‘wig-wag’ lever. The arrows shown in the image
above show the direction in which the scooter will move when the lever is operated as indicated.
Moving O
Insert the key and switch on the power and initially set the speed control to a low setting. The further
you pull the lever the faster the scooter will travel, but only to the maximum speed that has been
selected. Release the lever and the scooter will come to a smooth controlled stop.
Caution:
Do not switch o the power to stop the scooter as this will cause the transmission to lock
and the scooter will come to a sharp stop, which could possibly cause injury. This
procedure should only be used in an emergency.
Steering
Steering the scooter is light and easy. Ensure when starting o you give a wide clearance when
turning so that the rear wheels clear any obstacle that you are passing. When steering through limited
spaces such as a doorway or when turning around, turn the tiller handles where you want to go and
apply power gently. The scooter will turn very tightly, but will still move with complete stability.
Caution:
Never turn sharply at high speeds as it can make the scooter unstable. The maximum
speed should be set at 50%.
Caution:
Do not reverse onto a main thoroughfare.
Reversing
Before reversing ensure that the area behind is free from any hazards or obstructions. Adjust your
speed setting to a low setting before you reverse. Pull the left nger lever, and steer wide of all corners
and obstacles.
Dismounting
Before dismounting ensure that the key is turned to the o position.
Caution:
Please ensure that care is exercised when entering or leaving the scooter and that the tiller
is not used for support.

Ramps / Slopes
The stability of your scooter depends on several factors such as seat height, angle of gradient and the
users height and weight. When approaching an incline, do so directly and not at an angle and avoid
making turns where possible
Surfaces
Your scooter will perform well over many surfaces. However, avoid long grass, loose gravel, sand,
mud and ice.
Transferring
Lift up the arm-pad from the side you wish to leave or sit on the scooter. Use an aid for balance if
required. DO NOT use the tiller or armrests to support the full weight during transfers.
Caution:
Do not turn o the control key whilst the unit is in motion.
Storage
Your scooter should be stored in a dry environment, preferably a garage or shed. Tarpaulins and
covers may create condensation during certain weather conditions. If your scooter is to be stored for
prolonged periods, fully charge the batteries and disconnect the battery plugs.
Very cold weather can severely deplete battery condition (up to 40%). If left for any period during cold
weather it is very important that the scooter is fully charged before use.
Batteries
Charge the batteries completely (8-12 hours) prior to rst use.
The ROMA DENVER uses two 12Amp (S130) or 38Amp (S135), 12 Volt AGM batteries. The batteries
are located in a battery pack under the front of the seat. They can be easily removed by simply lifting
by the handle(s) on the top (S135 – remove the right side battery pack rst). Always make sure the
batteries are correctly relocated before use.
Low temperatures, rough terrain and the weight of the user can aect battery performance. Your
battery gauge is a guide only to the level of charge remaining in your batteries and will give its best
indication while the scooter is moving.
Batteries and Battery Chargers
Nithsdale
Wheelchairs

15
Note:
Batteries recommended by ROMA MUST be used if they need to be replaced. An
authorised ROMA dealer must carry out battery replacement.
Battery Charger
The battery charger is a 2-amp (S130) or 6-amp (S135) switch mode type o board. The battery
charging port is located on the front of the battery box (see image below). Before using your scooter
for the rst time be sure to fully charge the batteries, this may take up to 12 hours.
To charge the batteries connect the 3-pin male charger plug into the charging sockets. Plug the 3-pin
mains plug into a wall socket and switch on. A constant red light will show when the battery charger is
connected and charging is underway.
The green LED will light when the charging cycle is complete. Always turn o mains power to the
charger before disconnecting the plug from the battery box.
Caution:
Do not charge the batteries for longer than 12 hours. Always charge the batteries in a
well-ventilated indoor area.
You must still maintain charging the batteries even if the scooter is not to be used for a
prolonged period of time (2 to 3 weeks). Failure to do so could result in permanent
damage and render the batteries unusable.
Wherever possible do not interrupt the charge cycle until the batteries are fully charged.
Continual interruption can permanently damage the batteries. If the charging lead should
get damaged discontinue use immediately and seek a replacement from your dealer.
ONLY USE THE CHARGER SUPPLIED WITH YOUR SCOOTER. Do not leave the charger
plugged into to the charger port after the charge is complete. ALWAYS remove the keys
from the scooter when charging.
Disposing and recycling of used battery
Batteries must always be recycled correctly. Do not dispose of them with your
domestic refuge.
For further information regarding your nearest recycling facility please contact your
local authority.
