ASV Loader Manuals PDF
American ASV skid steer loaders have recently found a new home under the ownership of YANMAR.
In a recent strategic move, YANMAR successfully concluded an acquisition agreement with ASV Holdings Inc., a distinguished designer and manufacturer of ASV skid steer and crawler skid steer loaders, accompanied by a diverse range of attachments, accessories, and parts. This acquisition positions YANMAR to strengthen its foothold in the skid steer loader market.
As part of this acquisition, YANMAR gains control over an expansive industrial center, covering more than 22, 000 square meters. Additionally, YANMAR stands to benefit from an established dealer network in the United States, Canada, New Zealand, and Australia, extending its influence across North America and Oceania.
Although the acquisition was completed during the summer of 2019, the introduction of ASV products to the European market is currently progressing through the approval phase. This expansion into Europe holds the promise of delivering top-notch skid steer loader technology to a wider audience.
This acquisition signifies a noteworthy milestone for YANMAR, a Japanese company boasting a rich history dating back to 1912. By augmenting its portfolio with ASV's compact equipment range, YANMAR is well-positioned to meet the increasing demand for versatile and reliable machinery across various industries.
YANMAR has earned a stellar reputation as a manufacturer of exceptionally dependable mini-equipment, and their engines, carrying the same name, have garnered the trust of suppliers globally. This strategic partnership is expected to further cement YANMAR's position as a frontrunner in the compact equipment industry.
TROUBLESHOOTING
The most effective way to prevent a malfunction from occurring is to closely follow the recommended maintenance schedule and instructions throughout
the life of the machine. However,
if a malfunction does occur, finding the problem and fixing it
quickly are important. This section covers a select set of symptoms that may occur and suggests possible causes.
Problem
Machine will not crank over.
Possible causes:
1. Continuous high flow switch
activated.
2. Continuous low flow switch
activated.
3. Power quick-attach switch in
unlocked position. (SR-80)
4. Battery cables loose or corroded.
5. Ignition fuse blown.
6. Main starter fuse blown.
7. Starter relay malfunctioning.
8. Weak or dead battery.
9. Faulty continuous hydraulic
flow or power quick attachswitch.
10.Faulty ignition switch.
11.Faulty starter.
12.Loose, broken or disconnected wiring at key, relay or
starter.
13.Main power fuse (60/80 amp)
blown.
Problem
Machine cranks, but will not
start.
Possible causes:
1. Fuel tank empty, fuel filter
plugged or fuel line restricted.
2. Battery discharged (engine
rotates slowly).
3. Injection pump fuse blown.
4. Power relay (B) fuse blown.
(40 amp)
5. Faulty power relay (B).
6. Loose, broken or disconnected wiring at injection pump or
fuse.
7. Glow plugs not pre-heating
(look for black smoke).
a) Main glow plug fuse blown.
b) Glow plug relay malfunctioning.
c) Loose, broken, or disconnected wiring at ignition
switch, relay or glow plug
ground strip.
d) Faulty glow plugs.
8. Faulty ignition switch.
9. Loose, broken or disconnected wiring in starting circuit.
10.Loose, broken or disconnected wiring at fuel shutdown
solenoid.
11.Air in fuel system, or defective fuel injection pump.
Problem
Machine cranks, but will not start.
Possible causes:
1. Fuel tank empty, fuel filter
plugged or fuel line restricted.
2. Battery discharged (engine
rotates slowly).
3. Injection pump fuse blown.
4. Power relay (B) fuse blown.
(40 amp)
5. Faulty power relay (B).
6. Loose, broken or disconnected wiring at injection pump or
fuse.
7. Glow plugs not pre-heating
(look for black smoke).
a) Main glow plug fuse blown.
b) Glow plug relay malfunctioning.
c) Loose, broken, or disconnected wiring at ignition
switch, relay or glow plug
ground strip.
d) Faulty glow plugs.
8. Faulty ignition switch.
9. Loose, broken or disconnected wiring in starting circuit.
10.Loose, broken or disconnected wiring at fuel shutdown
solenoid.
11.Air in fuel system, or defective fuel injection pump.
Problem
Lift arm/bucket controls are
operational, but tracks will not
move.
Possible causes:
1. Leak in feed line to drive control joystick (pilot control).
2. Loose, broken or disconnected wire to DA control solenoid.
3. Drive control joystick (pilot
control) malfunction.
4. Low charge pressure.
5. Parking brake switch in on
position.
6. Faulty parking brake switch.
Problem
Tracks are operational, but lift
arms will not move.
Possible causes:
1. Continuous hydraulic flow
switch activated, sending oil
over relief (lift arms work, but
move slowly).
If auxiliary flow hydraulics work
check for:
a) Leak in feed line to lift arm
control joystick (pilot con
trol).
b) Lift arm control joystick
(pilot control) malfunction.
c) Hydraulic control valve
assembly malfunction.
If auxiliary flow hydraulics do not
work check for:
a) Main auxiliary relief
malfunction.
b) Faulty auxiliary pump.
Problem
Lift arms are operational, but
high/low flow auxiliary circuits
are not.
Possible causes:
1. Auxiliary hydraulic fuse
blown.
2. Faulty ground at chassis
crossmember.
3. Faulty auxiliary hydraulic
switch.
4. Faulty auxiliary hydraulic
solenoid at pilot generation
block.
5. Loose, broken or disconnected wire at fuse, auxiliary
hydraulic switch, or pin connector P10.
6. Auxiliary hydraulic pilot generation spool stuck in closed
position.
7. Faulty or improperly connected quick coupler.
8. Quick coupler block pressure
release stuck in down (open)
position.
Problem
Lift arms will not float, engine
labors and lift arms create down
pressure when float is engaged.
Possible causes:
1. Engine RPM too low.
2. Low charge pressure.
3. Lift arm control joystick malfunction (pilot control).
4. Hydraulic control valve
assembly malfunctioning.
Problem
Lift arm control joystick will not
lock into float position.
Possible causes:
1. Float magnet fuse blown.
2. Loose, broken, or disconnected wiring at fuse, float
detent magnet, or pin connector P8.
3. Faulty float detent magnet.
Problem

charge.
Possible causes:
1. Loose alternator belt.
2. Alternator fuse blown.
