General Maintenance (Recommended Schedule & Guidelines)
Daily/Weekly/Monthly (or as adopted)
Visual checks of seat top, back and bases - check all items for superficial or physical damage.
Three Monthly
Clean all items as detailed below check all fixings are seated correctly; inspect timber for serious damage and splinters.
Six Monthly
Secure all fixings; full clean as detailed below; check that seat/bench is firmly secured to the ground
Specific Maintenance Details
FSC Timber / Non-FSC Timber
Clean with a stiff brush once per year, especially in more exposed locations, in order to prevent a verdigris type build up on
the timber surface. Ideally this should be completed in early spring. During the cleaning stage, all exposed timber surfaces
should be inspected for splits and splinters. Any splinters and graffiti should be removed and the surface sanded with 100
grit sandpaper in order to remove any uneven / sharp edges or surfaces.
During the first few months after installation the tannin naturally occurring in the timber may leach out and cause a brown
staining on the bases. This may be removed with a light solution of household bleach and water.
Stainless Steel (polished stainless steel only)
Clean as required, but at least every three months, using a stainless steel polish and a lint free cloth. To remove ground in dirt,
a stainless steel finishing pad may be required.
Polyester Powder Coated
For general cleaning using a damp cloth and warm soapy water only. Scourers and abrasive cleaners are NOT suitable for
this type of finish and may damage it. Before using any cleaning agents to remove graffiti etc. try on a small, inconspicuous
area first to avoid causing more unsightly damage.
Granite / Concrete
Clean with a stiff brush once per year, especially in more exposed locations, in order to prevent a verdigris type build up on
the surface. Ideally, this should be completed in early spring.
Repairs
FSC Timber / Non-FSC Timber
For light damage, please see section on specific maintenance details above. For instances of heavy damage, the timber item
should be replaced. Please order against the part number reference in the reordering section towards the end of this manual.
Stainless Steel
Light damage (surface scratches etc.) can be removed using an emery pad (240 grit) and freeing oil such as ‘WD40’. Care
should be taken to follow the direction of the brushing grain. It is recommended that a trial repair be carried out on an
unimportant surface first. No corrosive cleaners or other abrasives should be used. Any contamination, particularly carbon
steel scuffs from vehicles, should be quickly removed to avoid corrosion.
Polyester Powder Coated Surfaces
For light damage (scratches, chips etc.) repair using touch-up paint to match original colour (available from Factory Furniture
Ltd). Paint application should be carried out in accordance with approved methods detailed by the paint manufacturer.
Please note that it is advisable to use professional painters to achieve best results when touching up larger areas. Products
for respraying larger areas are available from Factory Furniture Ltd.
Heavy Damage
In the event of serious damage to any component, replacements should be ordered from Factory Furniture Ltd. In this event
(or if the product needs to be disassembled for any reason), please contact Factory Furniture for detailed technical advice.

Tubular Base (Surface Fix)
Tubular Base (Sub-surface Fix)
Serpentine bench / seat on tubular bases (surface & sub-surface fix)
1. Install suitable foundation pads (see illustration) each with top face at ground level or 100mm below
finished ground level for sub-surface fix.
2. Unpack pair of bases and attach to the seat using the 8 no. M8 x 25mm button headed hex bolts and
tighten to 14Nm.
3. Attach the back unit (when supplied) to the seat unit using the 4 no. M8 x 40 button headed hex bolts,
apply thread lock to the bolt before inserting and then tighten to 10 Nm.
4. Position bench in correct orientation with bases centrally on foundation pads; then mark hole
positions through base plates.
5. Remove the bench; drill holes Ø12mm x 200mm deep (surface fix) or Ø12mm x 75mm deep or as
manufacturer’s recommendations (sub-surface fix).
6. Clear debris from holes.
7a. (Surface fix) Fill the holes to within approximately 35mm from the top with Hilti HY150 resin (or
similar). Lift the seat (with threaded anchor rods/capnuts in place) and carefully lower the anchors into
the holes, leave for two hours before using.
7b. Using a torque wrench, tighten nuts and washers over flange plates to 30Nm to fasten down the
bench.
8. (Sub-surface fix) Reposition bench unit and fix to foundation pads using 4 no. zinc-coated M10 x
75mm sleeve anchors tightened to 50Nm (or as per manufacturer’s instruction). Ensure bench remains
level during fixing process.
9. Check level & re-instate ground level if necessary (sub-surface fix).
IMPORTANT NOTE:
Ensure that stainless steel is protected during site cutting of stone – contamination from disc cutters will produce corrosion on
stainless steel components.

Elliptical Base (Detail same for seat)
Cylindrical Base (Detail same for seat)
Serpentine bench / seat on elliptical or cylindrical bases
1. Install suitable foundation pads (see illustration) each with top face at ground level.
2. Unpack pair of bases and attach to the seat using the 8 no. M8 x 25mm button headed hex bolts and tighten to 14Nm.
3. Attach the back unit (when supplied) to the seat unit using the 4 no. M8 x 40 button headed hex bolts, apply thread lock to
the bolt before inserting and then tighten to 10 Nm.
4. Position bench in correct orientation with bases centrally on foundation pads;
5. Gently pivot the bench onto its front and mark the positions of the holes in the base onto the foundation pads.
6. With the seat still on its front, fill the central anchor hole in each base to within approximately 35mm from the top with Hilti
HY150 resin (or similar) and insert Ø20mm x 400mm rebar anchor (supplied)
7. Bore Ø25mm x 230mm holes in the required positions in the foundation pads and remove any dust from the hole. Fill the
holes to within approximately 35mm from the top with Hilti HY150 resin (or similar)
8. Lift the seat and carefully lower the anchors into the holes, leave for two hours before using.
9. If there are any lumps in the foundation’s surface they will cause the seat to rock so it is recommended that if the foundation
is a rough surface, resin is applied around each base before fixing and toweled clean when settled.
IMPORTANT NOTES:
Ensure that stainless steel is protected during site cutting of stone – contamination from disc cutters will produce corrosion on
stainless steel components.
Granite must be treated with care, protect all edges when handling.
