Frequently Asked Questions - AME 842 VIKING

How to adjust the cutting height on the AME 842 lawn mower?

On the AME 842 model, the cutting height is adjusted electrically continuously between 30 and 85 mm. Use the dedicated control to adjust the height according to the grass length.

What tire pressure is recommended for the VIKING AME 842 lawn mower?

The recommended pressure is 0.6 bar (9 psi) for the front tires and 0.4 bar (6 psi) for the rear tires. Check it regularly on a flat surface.

How to clean the underside of the cutting deck?

After each use, rinse the underside of the cutting deck with water. If necessary, scrape off dried grass. Tilt the deck to vertical position for easier cleaning, after setting the cutting height to maximum and releasing the belt.

How to replace the mower blades?

Wear protective gloves. Always replace the two Y blades at the same time. Install the new blades with the folded edge facing inward. Tighten screw V to 9.8 Nm and screw W to 24 Nm.

What to do after a violent impact (stone, obstacle)?

Check that the blades are still at right angles to each other. If they are bent, loosen nut X, straighten the blade and replace bolt V with a new one. Check the belt and alignment. If in doubt, take the mower to a specialized service.

How to tilt the cutting deck for maintenance?

Set the cutting height to maximum. Lift the rear edge with one hand, push the safety latch and release the rear part. Repeat on the other side. Hook the tensioner, release the belt from the center pulley, then tilt the mower to vertical position.

What is the tightening torque for the blade screws?

The tightening torque is 9.8 Nm for screw V and 24 Nm for screw W. Use a torque wrench for precise tightening.

How to achieve optimal Multiclip effect?

For perfect results: mow frequently, run the engine at full throttle, keep the underside of the deck clean, use sharp blades, do not cut wet grass, and if the grass is tall, cut in two passes with two different cutting heights.

What to do if the grass is too tall?

Adjust the cutting unit so that the rear of the housing is higher than the front for easier discharge. Cut the grass in two passes: first at a higher height, then at the desired height.

How to install the mower for the first time?

Mount the front arms on the cutting deck with screws and washers. Attach the deck to the machine by screwing the arms into the steering knuckles. Route the belt over the center pulley, tension it with the tensioner, and attach the lifting spring. For the AME 842, plug in the electrical connector.

INTRODUCTION

This cutting deck is available as standard in two versions:

- with mechanical setting of the cutting height (AMM 842).

- with factory-fitted, electrical setting of the cutting height (AME 842).

ASSEMBLY

DECK ARMS

1. Install the left and right deck arms in the cutting deck's front two corners. Use the existing screw and flat washer (fig. 5). Tighten the screw. After tightening, it should be possible to move the deck arms up and down.
2. Do not hook the rear part of the deck arms onto the deck yet (See "Cutting deck" point 4 below).

CUTTING DECK

1. Place the cutting deck in front of the machine. Set the maximum cutting height.
2. Thread one of the deck arms onto the machine's steering knuckle (fig. 2-3). Place the flat washer on

the steering knuckle and secure with a locking pin. Repeat on the other side.

1. Force the V-belt onto the machine's centre pulley (fig. 6).
2. Lift up the deck's rear part past the catch until it drops down. When the weight of the deck is resting on the upper side of the catch, the installation is correct (fig. 4).
3. Tension the belt with the belt idler. The belt idler should be on the left side of the belt viewed from the driver's position (fig. 6).
4. Secure the lift spring in the implement lifter (fig. 5).
5. AME 842

Connect the electrical contact to the socket on the side of the machine (fig. 7).

SETTING

In order for the deck to cut evenly and attractively, it has to be correctly adjusted:

1. Make sure the air pressure in the tyres is correct: Front: 0.6 bar (9 psi).
   Rear: 0.4 bar (6 psi).
2. Place the machine on a level floor. Undo the screws on either side of the deck (fig. 8).
3. On the side of the deck arm are four short and two long lines. The upper long line (A) is the basic setting for a machine with 16" tyres (fig. 9).

Depending on the length of the grass, the deck can be adjusted in various ways:

4a. Cutting normal length grass:

Adjust the deck so that the front and rear edge of the cover are the same height above the floor. This position gives the best 'Multiclip effect', i.e. the grass is cut up best.

4b. Cutting long grass:

Adjust the deck so that the cover's rear edge is higher than the front edge. This position means that the deck can release the grass more easily at the rear edge.

1. After setting, tighten the screws properly.

USING THE MACHINE

CUTTING HEIGHT

AMM 842:

The cutting height can be varied between a number of fixed positions, from 30 to 85 mm.

AME 842:

The cutting height is continuously variable from 30 to 85 mm.

Note: Stated cutting heights apply when the machine is on a firm surface.

CUTTING TIPS

For optimum 'Multiclip effect', follow these tips:

• cut frequently.
• run the engine at full revs.
• keep the underside of the cutting deck clean.
• use sharp blades.
• do not cut wet grass.
• cut twice (with different cutting heights) if the grass is long.

SERVICE AND MAINTENANCE

PREPARATIONS

Unless otherwise stated, all service and maintenance must be carried out on a stationary machine when the engine is not running.

Prevent the machine from rolling by always applying the parking brake.

Prevent unintentional starting of the engine by always stopping the engine, disconnecting the spark plug cable from the spark plug and earthing it. Disconnect the negative cable from the battery.

MAINTENANCE TIPS

To make cleaning and maintenance easier, the cutting deck can be folded up:

1. Set the cutting height setting to the maximum cutting height.
2. Lift the rear edge of the deck with one hand (fig. 10).
3. Push up the catch and release the rear edge of the

deck (fig. 10).

1. Repeat the procedure on the other side.
2. Hook the belt idler arm on the mount (fig. 11)
3. Force the belt off the centre pulley.
4. Fold up the deck to the vertical position (fig. 12).

When the deck is folded down to working position, ensure that the catch drops down into position when the rear edge of the deck is lifted up (fig. 4).

CLEANING

After each use, the underside of the cutting deck should be rinsed off.

If the grass has dried solid, scrape clean the underside.

If necessary, touch up the underside with paint to prevent corrosion.

BLADES

Use protective gloves when changing blades to avoid cutting yourself.

Ensure that the blades are always sharp. This produces the best cutting results.

Always check the blades after a collision. If the blade system has been damaged, defective parts should be replaced.

Always use genuine spare parts. Non-genuine spare parts can entail a risk of injury, even if they fit the machine.

Install the blades according to fig. 13 where the blade edge is marked. The folded-up edge of the blade should be positioned inwards towards the blade holder.

The cutting system comprises two blade bars with two replaceable blades Y (fig. 14). When replacing blades, both should be replaced to avoid imbalance.

Install the new blades. Tighten screws V and W properly. Tightening torque: V - 9.8 Nm, W - 24 Nm.

In the event of a powerful collision, the blades may be bent out. Undo the locking nut X and fold back the blade. Install a new genuine break bolt V.

Tighten the locking nuts X and Z.

POSITIVE DRIVE BELT

Both blades are powered inside the deck by a positive drive belt.

If one of the blades has struck a solid object (e.g. a stone), the belt tension may be altered. This can lead to the positive drive belt 'over-meshing' which, in the long term, can damage the blades.

Following a powerful collision, always check that both blades are at right-angles to each other (fig. 13).

The working areas of the blades overlap each other. If the blades' position in relation to each other has been altered, there is a considerable risk of the blades striking each other. This can entail serious damage to the cutting deck.

If this is the case, take the machine and cutting deck to a service workshop for repair and inspection.
