2: Introduction
The Wheelbase is made of a strong and lightweight aluminium alloy, minimising weight
and providing a very rugged frame. The wheelbase provides a tilt in space facility and has
2 fixed rear wheels and 2 castor wheels at the front for easy steering. The wheelbase
comes in two sizes with corresponding interfaces to suit a range of different seats.
The Interface provides a very lightweight, easy to operate, quick release system that can
be fitted to a wide range of special seating systems. Please note the interface requires
additional framework to fit to a seat, and has been designed to take 19mm (3/4”)
aluminium or mild steel tube.
The interface can be quickly fitted and released from the wheelbase, which can be folded
for transport. The Snappi has been successfully impact tested as a wheelbase and
interface, with the Modular and Snug seating systems. When fitting 3
rd
party seating
systems to the Snappi, the manufacturer of the system must carry out a risk assessment
before use.
These instructions apply to all sizes.

4.1.1 Unfolding the Frame (original locks)
Standing at back of wheelbase, place
your foot on the rear crossbar X (see Fig
4.1.1.1) and lift handle labelled Y as far
as it will move.
This will open the frame.
Fig 4.1.1.1
Fig 4.1.1.2
Next locate the 2 plastic locking sliders.
These will be stowed in the “open” position
and are held in place by 2 small spring clips.
Press the 2 silver “Spring pins” in and
slide the 2 locking pieces down over the
lower tube sections.
Fig 4.1.1.3
Fig 4.1.1.4
The pins will spring through the holes in the
sliders and hold them in place (see Fig
4.1.1.4).

Snappi Wheelbase & Interface User Manual

Snappi Wheelbase Interface User Manual.doc
WARNING:
If the locking sliders are not in the correct position, or the spring pins do not
protrude thereby allowing the locking clips to move back up the frame, then the
frame may collapse in use.
Folding the wheelbase: To unlock the frame and fold the wheelbase, reverse the above
instructions.
4.1.2 Unfolding the Frame (Spring loaded locks)
Standing at back of wheelbase, place
your foot on the rear crossbar X (see Fig
4.1.2.1) and lift handle labelled Y as far
as it will move.
This will open the frame.
Fig 4.1.2.1
Fig 4.1.2.2
Once the frame is almost open, the 2 plastic
frame locks will engage with the angled
sections of the lower frame.
Continue to unfold the frame; this will force
the locks up the tubes. There will be some
resistance, as you will be working against the
locking springs.
Once fully open, the frame locks will
snap shut over the front frame, securing
the frame in the open position.
Always check that both locks are fully
closed. In the locked position the guide
bolt ‘B’ will be sat in the top of the slot ‘A’
on the side of the slider as shown (see
Fig 4.1.2.3). If there is any slot visible
above the guide bolt, push the lock down
by hand until it will not move any further.
Fig 4.1.2.3

Fig 4.1.2.4
To fold the frame:
Standing beside the frame, pull up the 2
locking sliders as shown (see Fig 4.1.2.4).
Whilst holding the locks open, push down
with your arm on the upper frame or push
handle, so that the frame starts to fold.
Release the locking sliders, and fold down
the frame by moving the push handle down
as far as it will move.
IMPORTANT:
Always check that BOTH frame locks are fully closed before using the frame. If they
are not properly engaged, the frame could collapse during use.

4.2 Brakes
Fig 4.2.1
To apply the brake, put your foot on the top
of brake bar ‘X’ (see Fig 4.2.1) and push
down as shown. The brake will flip down
onto the wheels and lock them.
To release the brake, simply hook your foot
between the middle raised portion of the
brake bar, and the frame crossbar. Then, lift
the brake bar with your foot until it flips back
and stops against the brake stop pins. You
may find it easier to use your hand instead
of your foot to release the brake. If
operating the brake by hand always hold the
brake by the raised section in the middle of
the bar.
Fig 4.2.2
WARNING:
The brake mechanism is spring loaded so care must be taken when operating it.
When operating the brake mechanism ensure that you always keep a firm hold of
the pushchair, keeping your hands well away from the brake mechanism.
Always put the brake on when placing the child in or taking them out of the seat.
Do not leave the pushchair on a slope, even with the brake on. Always ensure that
the pushchair is on level ground to prevent risk of injury to the occupant.
Do not leave the brake on when the pushchair is not in use as this will damage the
rear wheels.
Tyres:
As standard the Snappi wheelbase is supplied with solid tyres, however pneumatic tyres
are also available as an option. If your pushchair is supplied with pneumatic tyres these
need to be regularly checked and inflated if necessary using a hand or foot pump. The
operating pressure for the tyres is 36 PSI (note: do not inflate the tyres above 36 PSI). Do
not use high pressure air lines or mechanical pumps as used in garages to inflate the
tyres.

4.3 Using the Tilt in Space facility
Fig 4.3.1
To operate the tilt in space mechanism,
place your hand over the push handle
adjustor, and lift the lever ‘L’ (see Fig 4.3.1)
as shown.
This will open the gas strut and tilt the mid
section. Note; The speed of tilt can be
controlled by varying the pressure applied at
lever L.
When tilting with a seat fitted, use your
other hand to support seat as it tilts.
Fig 4.3.2
Fig 4.3.3
To reset the tilt mechanism, hold down lever
L and push down firmly on the front of the
frame interface as shown (see Fig 4.3.3).
Once the mid section is in the desired
position, release lever L. For a 90-degree
‘flat’ position, move the mid section so the
gas strut is fully closed and it will not move
any further before releasing the tilt lever.
IMPORTANT:
 Always ensure any harness provided for the child is used and correctly adjusted before
reclining or returning the seat to a more upright position.
 Always support the seat when tilting, as the gas springs can be quick to operate. If the seat is
not supported, is may move swiftly and could cause the occupant distress.

4.4.1 Interface safety catch
The interface includes a 2-stage latch that comprises a main latch and a second safety
latch that prevents accidental release of a seat from the chassis.
The safety catch must be correctly set before the main catch can be operated:
How to operate the safety catch:
Fig 4.3.1
Safety Catch Locked
The safety catch clip is located under the
front right corner of the seat near to the
release lever (See Fig 4.3.1).
Definition of components:
X: Pull handle
Y: Locking Pin
To release the safety catch, pull the handle
“X”, and turn it 90 degrees so that the pin
“Y” is fully retracted.
To lock it, pull “X” and turn 90 degrees in
the opposite direction, so that pin “Y” is fully
protruded and sits behind the interface main
catch “B” (see fig 4.3.3 on next page).
Fig 4.3.2
Safety Catch unlocked
Important:
When fitting or removing the seat, the carer / parent must first ensure that the safety
catch pin is set in the “unlocked” position. It will not be possible to fit or remove the
seat if the latch is “locked”, and attempting to do so may cause damage to the
chassis or the seat.
Once the seat has been fitted, the carer / parent must always lock the safety catch.
Note:
A warning label is positioned on the front right hand portion of the tilt frame on the
chassis, to remind carers to lock the safety catch.

Fig 4.4.2
Next, push down on the interface so that the
clips snap over the front stainless steel
bushes on the frame interface. Note that
due to the design of the frame interface, it is
not possible to fit the interface backwards. If
fitted the wrong way around the clips will not
close and it will not sit down into the frame.
Once the interface is fitted, always lock the
secondary catch as detailed in section 4.4.1
To release the interface, unlock the
secondary latch, and then lift the release
lever up as shown (See Fig 4.4.3). This will
open the clips and lift them away from the
frame in one movement. Then simply lift the
rear hooks off from the frame.
Fig 4.4.3
IMPORTANT:
 Always ensure that the interface clips have latched fully. To test this, press down on the
release lever when fitted and make sure the clips will not move.
 Do not attempt to fit the interface backwards. It will not lock in a rearward facing position.
 Always ensure that the interface is firmly held on all 4 fixing points (the 4 stainless steel
bushes on the frame interface).
 The interface is spring loaded, so ensure your fingers are clear of the clips before fitting.
