Forest Management

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
Clean with a sti 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 grati 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 & Galvanised
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 grati etc.
try on a small, inconspicuous area first to avoid causing
more unsightly damage.
Granite / Concrete
Clean with a sti 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
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 scus from
vehicles, should be quickly removed to avoid corrosion.
Polyester Powder Coated & Galvanised 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. Should further assistance be required (or if the
product needs to be disassembled for any reason),
please contact Factory Furniture for detailed technical
advice.

Installation Instructions
All installation works to be carried out by
competent personnel - install as complete
unit.
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. Fully assemble bench / seat following
instructions on pg. 5 of this document.
3. Once assembled position bench / seat in
correct orientation with bases centrally
on foundation pads; then mark hole
positions through base plates.
4. Remove the bench; drill holes Ø14mm
x 130mm deep (surface fix) or Ø12mm
x 75mm deep (sub-surface fix) or as
manufacturer’s recommendations.
5. Clear debris from holes.
6.a. (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.
6.b Using a torque wrench, tighten nuts and
washers over flange plates to 30Nm to
fasten down the bench.
7. (Sub-surface fix) Reposition bench /
seat 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.
8. 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.

Installation Instructions
All installation works to be carried out by competent
personnel - install as complete unit.
Serpentine bench / seat on elliptical bases
1. Install suitable foundation pads (see illustration)
each with top face at ground level.
2. Fully assemble bench / seat following instructions on
pg. 5 of this document.
3. Once assembled position bench / seat in correct
orientation with bases centrally on foundation pads;
4. Gently pivot the bench onto its front and mark
the positions of the holes in the base onto the
foundation pads.
5. 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)
6. 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)
7. Lift the bench / seat and carefully lower the anchors
into the holes, leave for two hours before using.
8. 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 NOTE
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.
