Visual checks of ring, frame and grille - check all items for superficial or physical damage.

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 tree guard is firmly secured to the ground
Specific Maintenance Details
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.
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 graffiti etc. try on
a small, inconspicuous area first to avoid causing more unsightly damage.

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 scuffs from vehicles, should be quickly removed to avoid corrosion.
Galvanised Surfaces
For light damage to hot dipped galvanised finishes repair using a high performance cold galvanising zinc spray
(70% zinc or above). Spray application should be carried out in accordance with approved methods detailed by
the product manufacturer. Please note that it is advisable to use professional painters to achieve best results
when touching up larger areas.
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.

Installation Instructions
ALL INSTALLATION WORKS TO BE CARRIED OUT BY COMPETENT PERSONNEL - INSTALL AS COMPLETE UNIT
Circular tree guard set out
Circular Tree Guard & Grille (sub-surface fix only)
1. Dig appropriate sized hole for tree (approx. two times the width of the tree root ball and the same depth as
the ball)
2. Position and correctly orientate tree grille frame centrally over hole so that the top of the frame is at ground
level. Ensure that frame is stable
3. Check level of frame & re-instate ground level up to frame edge (ideally setting frame in concrete for stablilty).
4. Position tree in centre of hole and back fill over root ball. Do not back fill too far over the top of the root ball
or this may cause the trunk bark to rot, damaging the tree. Lightly tread down backfill to secure tree.
5. Attach the two grille panels to the grille frame using 8 no. M8 x 20mm anti-vandal button head bolts. Tighten
to 14Nm.
6. Fix down both halves of the guard frame onto the grille ring plates using 10 no. M8 x 20mm anti-vandal
button head bolts. Tighten to 14Nm.
7. Attach the two joining plates to the top of the frame (using 4 off 25mm x S14 pan head screws) to secure the
two frame halves together.
8. The tree guard fixing eyes can be used to secure the tree trunk if necessary.
IMPORTANT NOTE:
Ensure that stainless steel is protected during site cutting of stone – contamination from disc cutters will
produce corrosion on stainless steel components.
