Care and Maintenance
IMPORTANT:
Tree spade must be lowered to the ground and switched off when
doing cleaning, maintenance or repair work !
Use original spare parts only !
The tree Spade must be inspected by an expert on
operational safety once per year !
Do not alter the design of the tree spade without having
consulted the manufacturer !
Check screws regularly on tight fit. Tighten firmly, if necessary !
5.1
Blade Guides
Thanks to the plastic lining the spade guides do not require special care.
Once the plastic lining has been worn, to the point were the heads of the countersunk
screws are even with the surface of the plastic linings, they must be replaced to prevent
the screws from damaging the blades.
IMPORTANT:
Keep the guides cleaned.
5.2 Lubrication
Once per week lubricate all greasing points with lithium-based grease,
as per lubrication chart, Page 19
5.3
Hydraulic Oil Supply
Check l
evel of hydraulic oil regularly. For checking, retract all blades “up”
and lower the tree spade to the ground. If in that position the oil level is
below the mark of the sight glass, oil must be refilled.
5.4
Hydraulic Hoses
All hydraulic hoses must be inspected at least once per year. Damaged hoses
must be replaced. At least after 6 years all hoses must be replaced.
5.5
Cylinders
In case the tree spade is not getting used for two weeks, all piston rods of the hydraulic
cylinders must be cleaned and covered with a preserving oil film.
