4 Tooling
Most of the operations described in the Manual can be performed
with simple hand tools and measuring instruments that mechanics
know quite well. Use the tools exactly as prescribed. Keep them
clean and tidy�
To maintain SNOWDOG, wrenches and heads with sockets and
ratchets of the following metric sizes may be needed, 10, 12, 13,
14, 17, an INBUS wrench of 5 mm, 3 mm and a cross screwdriver.
You may also need pullers.
4.1 Screwdrivers
Use the screwdriver for screwing and unscrewing screws. Do
not try in any other way to remove parts with a screwdriver.
Damaged or worn-out screw drivers should be replaced. When
using a screwdriver with the worn tip, it is quite likely that the
fastening element will be damaged, and it will subsequently
complicate its removal�
4.2 Wrenches
Open-end wrenches, box wrenches and combination wrenches
may be of various types and sizes.
In most cases it is preferable to use a box wrench, particularly for
final tightening of a mounting element.
!
WARNING
DO NOT USE HEADS FOR HAND TOOLS IN
WORKING WITH PNEUMATIC TOOLS. THISMAY
CAUSE THEIR DESTRUCTION AND INJURY.
USE EYE PROTECTION WHEN WORKING WITH
PNEUMATIC TOOLS.
4.3 INBUS wrench
With these models an INBUS wrench is used to adjust and
customize the brake system. A key with the size S=5 mm and 3
mm with a short handle (A~100 mm) or any other hex crest with
the size of 5 and 3 mm with ratchet should be used.
5 General principles of
troubleshooting and performance of
works
Most of the operations described in the Manual are quite simple
and can be performed given the basic tool handling skills.
However, when performing major operations to dismantle the
elements you should reasonably take an unbiased look at your
ability�
1�
In working with the engine and suspension parts
SNOWDOG needs to be securely fastened�
2�
For all identical parts they need to marked on
SNOWDOG. On the mating surfaces marks indicating
their position relative to each other should be applied.
3�
Removable wiring and connectors should be marked
with adhesive tapes and markers.
4�
The treated surface should be protected against
physical damage and corrosion. Avoid contact with
gasoline and other chemicals on the treated surface.
5�
When working with stubborn and rusted bolts use a
penetrating lubricant, for example, WD-40. If possible,
avoid any strong thermal effects. At high temperature
parts can melt and be deformed as well as the painted
surfaces and plastic parts may be damaged.
6�
If you are having trouble removing parts, you should
determine the cause, eliminate and then continue
with the removal.
7�
Close all openings to prevent debris and foreign items
from getting into the engine.
8�
Before starting the procedure read the instructions
guidelines and compare the parts with the pictures.
9�
The term “replace” refers to the replacement of faulty
parts with non-defective ones. The term “rebuild”
means the removal, disassembly, troubleshooting,
measurement, repair and assembly of parts.
10�
The term “front side” in the Manual refers to the front
part of SNOWDOG. The front side of a component
is part of the component closest to the front part of
SNOWDOG. The left and right sides are indicated
relative to the driver’s position when he stands in a
sleigh heading forward.
11�
Some procedures will require a hydraulic press or a
special puller� Do not attempt to perform a similar
procedure with any improvised means, it may cause
damage of SNOWDOG.
12�
It is much easier to repair SNOWDOG if you wash
it before starting repairs. Use a degreasing agent.
Before its use, consult the instructions for use.
