4: Preparing for use and operation
The following pre-delivery procedures should be carried out to check that the seat unit has
not suffered damage during transit and that all features operate satisfactorily. Refer to the
user manual for detailed instructions on performing each action.
4.1 Fitting the seat to the chassis
Fit the seat unit into the chassis following the instructions in section 4.3 of the seat user
manual (note the mounting system is the same for all chassis that the Snappi Seat fits to).
Checks:
•Check that the spring clips move freely and snap back to their closed position when
the lever is released
•Make sure the seat interface latches down and locks securely to the frame
•Check that the secondary latch mechanism functions correctly
•Check that the seat interface releases correctly and that there is not excessive
friction on the lever when releasing it from the frame
4.2 Seat back recline:
Test the seat back recline mechanism is working correctly by following the instructions in
section 5.1.3 of the seat user manual.
Checks:
•Make sure the gas spring moves freely through its entire range of motion when
released
•Ensure that the gas spring locks when the lever is released.
•Check that the fixing bolts for the gas spring are secure and that there is not
excessive play between the gas spring and the mounting points on the seat when
locked.
4.3 Seat standard adjustments:
All adjustments to the seat are made using hand wheels, or the 5mm hexagon key provided.
Test the adjustment ranges of the seat base, hip width, footrest depth, footrest angle and
back height as detailed in sections 5.1.1 –5.1.3 of the seat user manual.
Checks:
•Ensure all elements are free to move over their entire adjustment range (note that the
cover and harnessing may need adjusting to allow this- instructions on how to adjust
these are given in section 5 of the user manual)
•Check that all elements lock correctly
•Check that the framework is square and has not been damaged during transit.

Snappi Seat Standalone Workshop Manual.doc
5: Final checks
1. Check that the pelvic strap or harness is secure and adjusted correctly.
2. Check that the cover is correctly fitted.
3. Check that the seat unit is located and locked correctly in the chassis.
4. Ensure the safety catch is locked.
6: Maintenance
Should a problem be found when carrying out the regular checks, it should be immediately
reported to the issuing authority or Tendercare Ltd.
6.1 Routine maintenance
The user’s family can easily carry out the following tasks. No tools are required.
1. Always wipe the seat frame dry. Never put it away damp.
2. Check operation of the reclining mechanism (weekly).
3. Clean the seat frame when necessary (we suggest at least once a week).
If you find any faults refer to your issuing authority or Tendercare Ltd.
6.2 Six-monthly maintenance
Only someone who is a competent tradesman or repairer should carry out this work. If a
major fault is found stop using the seat until it has been corrected.
1. Examine nuts, bolts, pivots and frame plugs for tightness and general condition.
2. Check the Interface fits securely into the frame, and that it is not worn or damaged.
3. Check the interface clips to ensure they can rotate freely and that the springs return
the clips to the closed position when released.
6.3 Three-yearly maintenance
1. The seat gas strut release head is cast aluminium and so we recommend this is
routinely replaced every three years.
For all other repairs refer to your issuing authority or Tendercare Ltd.

Snappi Seat Standalone Workshop Manual
Document No: 053-08 v2 Page 9 of 49 March 2019
Snappi Seat Standalone Workshop Manual.doc
7: Repairs
Only an authorised repairer should carry out the following repairs.
1. Repairs: For all repairs contact your issuing authority
2. Major repairs: For all major repairs e.g. bent or damaged frame, the seat should be
returned to the factory. Contact Tendercare ltd, customer services on 01903 726161,
or email to [email protected]
3. Factory replacement components should be used in all repairs. These are available
from Tendercare. Please refer to the parts lists at the end of this manual (section 11)
for details of replacement parts.
Important points when performing a repair:
1. Do not reuse Nylock nuts, always replace with a new nut
2. Always use Loctite thread locking compound grade 241 or 243 on all threads when
reassembling any part of the system.
3. Always use the recommended component parts available from Tendercare Ltd.
4. Do not attempt to correct bent framework or perform any modifications to welded
parts. If any main framework sections are bent or damaged please return the product
to the factory.

7.1: Seat gas spring/strut
Replace the gas spring if it is damaged or worn. Please note, as the gas strut release head
is cast aluminium, we recommend this is replaced every three years.
To remove the gas strut (shown in Fig 7.1.1):
Fig 7.1.1
•Lift the seat onto a suitable
workbench and sit it on its interface
with the seat back angle set at 90
degrees.
•Using 2 x 13mm spanners undo the
gas strut fixing bolts. Take note of the
position of the washers and spacers.
•Remove the release lever; undo the
release head by placing a bar (e.g.
shank of a screwdriver) through the
mounting hole in the head and loosen
with a 13mm spanner as shown in Fig
7.1.2.
•Next, unscrew the gas spring from the
head and remove the release lever.
Fig 7.1.2
•To reassemble the new gas spring,
place the release lever into the head,
and screw in the gas spring so that
the pin on the end of the gas spring
locates into the notch in the lever.
Note: for Snappi seats fitted with the
dynamic gas strut, you will need to
place the dynamic strut restrictor
between the body of the gas strut and
the m8 lock nut (see Fig 7.1.3).

Fig 7.1.4
•Tighten the m8 lock nut until there is
no movement between the pin and
release lever, then unscrew the gas
spring by ¼ of a turn. This ensures
that there is the correct amount of
play between the pin and release
lever. Do not over tighten
•Finally secure the release head by placing a bar though the mounting hole and
tighten with the 13mm spanner.
IMPORTANT:
❖Ensure that there is a small amount of play between the release lever and pin on the end of the
gas spring. If this is too tight, the gas spring may not lock correctly, or could have the
tendency to ‘creep’ when in a locked position.
7.1.1: Lock the Back Recline
The following instructions detail how to remove the back recline adjustment lever in order to
lock the back recline in a single position.
Fig 7.1.1.1
•First, position the back rest to the
desired fixed position* (please refer to
the section 5.3.1 of the user manual
for how to adjust the angle of the
backrest).
•Next, use a 13mm spanner to loosen
the black nut on the gas strut (3 turns
should be sufficient) as shown (see
Fig 7.1.1.1, left).
M8 lock nut

•Using a pair of 13mm spanners,
remove the M8 bolt that secures the
top of the gas spring the back rest of
the seat as shown (see Fig 7.1.1.2,
right). Take note of the positions of
the spacers, washers and nuts.
Fig 7.1.1.2
Fig 7.1.1.3
•Hinge the gas spring away from the
back of the chair (it will pivot on the
lower bolt) and unscrew the head a
few turns and then remove the lever.
•Screw the head back onto the gas
spring and lock in place using the
black nut and a 13mm spanner.
•Fix to the backrest using the M8 bolt,
replacing the washers and spacers in
their original position.
Fig 7.1.1.4

Snappi Seat Standalone Workshop Manual.doc
Important:
*The Snappi Seat is only crash tested with the backrest set to a 90-degree angle. If the backrest angle
is fixed at any angle other than 90 degrees, the seat can no longer be used for transport in an adapted
vehicle.
7.2: Seat Interface
Replace the interface clips if they are damaged or bent; replace the springs if they are
stretched or overly soft in operation.
IMPORTANT
The seat interface uses 2 strong torsion springs that are under load. Care must be taken when working
on the interface clip mechanism. The following instructions are the recommended method for
dismantling the assembly to safely release the tension on the springs. If you are not confident to work
on this assembly, please return your frame to the Tendercare factory.
To dismantle the interface:
•Loosen the front screws from the
mounting using a 4mm hexagon key
as shown (right).
•Remove the rear as the tension on
the 2 torsion springs must be
released before removing the clip
mechanism from the interface frame.
Fig 7.2.1
7.2.2
To release the tension on the springs:
•Rotate the clips forward and lift the
frame so that it pivots on the 2
loosened front screws. Keep lifting
until the 2 spring arms are released
from the interface frame cross bar, as
shown (left)
•Once the springs have been released, remove the 2 front screws using a 4mm
hexagon key. The interface clip assembly can then be easily taken apart by sliding
off the 2 mounting blocks, springs and washers.

Snappi Seat Standalone Workshop Manual

Snappi Seat Standalone Workshop Manual.doc
Fig 7.2.3
Take note of the position of the 2 chamfers of the mounting blocks as these MUST be put
back in the correct orientation or the interface mechanism will not function properly.
Also take careful note of the orientation of the springs- the springs are handed and must be
re-fitted correctly or there will not be enough tension on the mechanism to close the clips.
To reassemble the interface, follow the reverse of these instructions and test as detailed in
section 4.4 of this manual.
7.3: Knee Angle Adjustor
Replace the seat knee angle adjustor if damaged or worn.
The replacement knee angle adjustor comes
supplied with: 1 x M5 x 30mm socket button
bolt, 1 x M5 x 35mm socket button bolt, 2 x
M5 Nylock Dome nuts, 4 x M5 Form A
Washers
Fig 7.3.1
Fig 7.3.2
Set the footrest to a horizontal position (i.e.
in line with the seat base) and place the
whole seat onto a flat surface.
Undo the nut and bolt securing the footrest
rod, taking note of the position of the bolt
head and washers, using a 3mm hexagon
key and an 8mm spanner.

Snappi Seat Standalone Workshop Manual
Document No: 053-08 v2 Page 15 of 49 March 2019
Snappi Seat Standalone Workshop Manual.doc
Next separate the footrest rod from the
adjustor as shown (right).
Fig 7.3.3
Fig 7.3.4
Undo the rear bolt securing the knee angle
adjustor (this bolt goes through the play tray
adaptor), again taking note of the position of
the washers and nuts etc. Remove the bolt
then slide the knee angle adjustor off the
frame. Note it may be helpful to loosen the
rear bolt securing the play tray adaptor if it is
difficult to slide the angle adjustor off the
frame.
Finally, slide the new adjustor onto the frame, and secure using the new bolts and nuts as
supplied (never re use nylock nuts). Please ensure that the rear fixing bolt is tightened again
if loosened in the previous step, and that the frame fixing is placed through the play tray
adaptor as before.

off the stems (see Fig 7.4.1.3).
Using a 3mm hexagon key and an 8mm
socket or spanner, remove the M5 bolt
securing the stem to the knee angle adjustor
(as shown in Fig 7.4.1.4). Take note of the
position of the washers. Then remove the
stems.
Fig 7.4.1.4
To fit the new stems: Follow the reverse of this procedure and fit with a new Nylock dome
nut (never re-use Nylock nuts).
7.4.2: Footrest Tray:
Remove the footrest slide assembly from the pushchair, to do this:
•Remove the 2 x self-tapping screws from the end of the footrest stems.
•Loosen the footrest slide locks
•Slide the footrest assembly off the end of the stems.
