Hydraulic Lockout Control

WARNING

Always place the hydraulic lockout control securely in the LOCK position before leaving the

operator cab. If the hydraulic lockout control is not in the LOCK position any unintended

touch of the control levers may cause serious injury or death. Take care not to touch either

joystick when you pull (up) or push (down) the lockout control.

The hydraulic lockout control (1) is a device used to lock

out the control levers of all work equipment to include the

swing system, travel system and optional attachments.

1

•

To engage the machine in the LOCK position push

down the hydraulic lockout control. The machine

will not move even if you maneuver the controls.

•

Pulling up the hydraulic control level places the

machine in the UNLOCKED position where the

machine moves in accordance with the joysticks

and other control levers.

Fig. 3-16

3-17

Cab Interior

SY335 Excavator

WARNING

If any part of the machine moves when the hydraulic lockout control is engaged, it indicates a

failure in your machine. In this case, immediately engage the hydraulic lockout control and

stop the engine. Contact your Sany distributor to solve this problem.

Emergency Stop Switch

The engine emergency stop switch (1), which is located just

below the hydraulic lockout control (2), is normally on

during regular operation of the excavator.

In case of an emergency, press the emergency stop switch

to shut down the engine. The hydraulic lockout control can

be used to lock out the hydraulic system while the engine

emergency stop switch (1) is used to ensure the safety of

the engine.

Joystick Controls

WARNING

Never expose any part of your body outside the window, this may put you in danger of being

hurt by the boom if the joystick is moved unexpectedly. If a window is broken or missing,

replace it immediately.Know the positions and functions of each joystick control. Unexpected

movement of the machine could cause personal injury or death!

There are two operating modes available for the joysticks;

the SAE (Society of Automotive Engineers) mode (see

page 3-19) and BHL (Back Hoe Loader) mode (see page 3-

19). To chose between these two modes follow these

instructions.

SAE/BHL Selector Switch

The SAE/BHL selector switch (a) is located below the

engine air cleaner inside the left side front cover.

Fig. 3-18

The SAE/BHL selector switch (b) swaps the control of the

boom and the arm from one joystick to the other. The position shown (b) is the SAE mode position. To change to

the BHL position pull the pin up (c) and rotate the bar to the left. Release the pin to lock the bar in place.

Fig. 3-19

•

In SAE (Society of Automotive Engineers) mode, the arm is controlled using the left joystick and the

•

In BHL (Back Hoe Loader) mode, the arm is controlled using the right joystick and the boom is controlled

using the left joystick (see page 3-21).

When travel control levers and joystick controls are in neutral, any maneuver of the control lever will set the engine

speed to go up to the speed set by the throttle. If travel control levers and joystick controls stay in neutral, engine

speed will decrease by 100 rpm. About four seconds later the engine will drop to the level (about 1,400 rpm) set for

automatic deceleration (see page 3-24).

Once you release the control lever or joystick, the machine goes back into neutral and the machine stops.

Travel Controls

WARNING

Take extra care when driving or steering the machine with pedals. Do not put your foot on any

pedal when they are not used.

1

The machine Travel Controls group consists of the

following pedals:

1. Travel control levers

2

2. Travel control pedals

3. Foot rest

3

4. Auxiliary equipment control pedal

Fig. 3-24

4

The control levers/pedals are used to change travel direction

of your machine. The description in brackets is given for

pedal operation.

1. Forward travel:

Push the control lever (pedal tilts forward)

2. Backward travel:

Pull the control lever (pedal tilts backward)

3. N - (Neutral Position): Machine stops.

Fig. 3-25

3-23

Cab Interior

SY335 Excavator

Always check the direction (4) of track frame before you

maneuver the travel control levers. (If the sprocket is in the

rear, the track frame faces the front.)

When the track frame faces backward remember that the

travel direction will be opposite to the maneuvering

direction of travel control lever. (Machine moves forward

4

when you pull control levers and backward when you push

them. The left and right directions are reversed too.)

Fig. 3-26

Automatic Deceleration Function

The automatic declaration mode is automatically activated when the machine is energized. When no control levers

are operated within 5 seconds with the engine running, engine speed drops to idle to cut fuel consumption and

reduce noise. When any of the control levers is operated or fuel control dial is adjusted while the engine is idling,

engine speed returns to previous level or the newly set level automatically. With the automatic deceleration

function the travel control levers can be used to change engine speed in the following way.

•

When travel control levers and joystick controls are in neutral position, engine speed will drop to medium

level even if fuel control dial is set above medium speed. If you maneuver any control, the engine speed

will rise to the level set on the throttle.

•

If travel control levers and joystick controls are in neutral the engine speed will decrease by 100 rpm.

About four seconds later engine will drop to the level (about 1,400 rpm) set for automatic deceleration.
