general
Correct tension of a belt.

Belts must be tensioned differently depending on their condition (flat belts, V-belts, toothed belts, etc.).

However, the following rule applies to most belts:

The drive belt may move when the tension is correct and the lateral pressure is 2 kg. Let the belt compress approx. 2mm.

If you have any questions about belt tension, please contact the Holzmann customer service (after-sales service or workshop)

Commissioning of a 400v machine
All 400V machines

400V machines always must be connected with 3 phases and one grounding.
With 4-wire wiring, the neutral conductor is omitted, with 5-wire wiring, a neutral conductor must also be connected (please also note this for any extra used extension cables)!

400V motors running only on 2 phases get hot very quickly and thus trigger the overload protection or break.

What to do if the machine is running but has no power? Machine switches off or overheats?
All 400V machines

Please check the electrical connection and the supply line of your machine (also a possibly used extension cable).

400V machines always must be connected with 3 phases and an earthing.
With 4-wire wiring, the neutral conductor is omitted, with 5-wire wiring, a neutral conductor must also be connected!

400V motors running only on 2 phases become very hot quickly and thus trigger the overload protection or break.

Please also check if possibly present drive belt is sufficiently tensioned.

 

My 230V machine is no longer working, fuse fails?
All 230V machines

Please check the carbon brushes from the motor of your machine. These are wear parts which must be replaced sooner or later depending on the operating hours. If you have a machine with an induction motor, please contact our Holzmann customer service. (service@zipper-maschinen.at)

FI, automatic circuit breaker, automatic circuit breaker drops out when the machine is switched on?
All 230V machines

Please check if you are sufficiently fused for the machine used. 230V machines with a high motor power or high starting current require a 16 amp fuse with class C tripping characteristic "slow blow".

If you are not equipped with a C-16 fuse, please contact an electrician. Work in the distribution box may only be carried out by a specialist.

What is S1 or S6? Why is the performance data different?
All 230V/400V machines

These are the rated operating modes of electric motors. A rated operating mode is a basic description of the load on an electrical machine. The nominal operating modes are defined in the international standard IEC 60034-1, which corresponds to the European standard EN 60034-1 and various national standards.

Since it would be uneconomical to design all machines for every conceivably difficult task, nominal operating modes have been defined in order to be able to clearly identify both a suitability for difficult conditions and a restriction to particularly light tasks.
S1 = continuous operation with constant load, S6 = periodic operation with load and speed changes (cooling phases).

Please note that these specifications always refer to one and the same motor and that these machines are not offered with different motors.

Engine does not start
Construction machinery/electric generator/shredder

Please check the engine oil level. The engine is equipped with an oil low protection, which does not release the ignition if the oil level is too low. The engine oil must be filled up until the oil can be seen at the filler opening by the thread.

What engine oil is used for the 4-stroke engines?
4-stroke engines

The following oils can be used for the 4-stroke engines of the Zipper machines.

15W40, 10W40, 10W30, SAE30

Plate compactor - engine does not start
Plate compactor

Please check the engine oil level.

The engine is equipped with an oil low protection, which does not release the ignition if the oil level is too low. The engine oil must be filled up until the oil can be seen at the filler opening by the thread.

The engine dies after a short running time or does not produce any power
Plate compactor

Please clean the air filter, this can quickly become dirty in very dry and dusty environments. The motor then gets too less air and it does not run properly.

If the plate compactor simply dies off after a short time, please check if the fuel tap is open. 

What is the second oil filler hole on the engine for?
Plate compactor

Both filler openings serve the same purpose. The engine is installed reversed on other models, so there must be a filler opening on both sides of the engine.

ZI-RPE90C What is the sealed hose on the front of the engine used for?
Plate compactor ZI-RPE90C

This hose can be used to drain the oil when changing the oil.

Minidumper – The gears are hard to shift
Minidumper

The transmission of our minidumpers is not synchronized, therefore it might happen that the gears are a bit harder to shift. This has nothing to do with a defect. Please note that the gears should only be engaged when the dumper is standing still.

Minidumper – Steering works unevenly
Minidumper

The steering effect can be adjusted and balanced on the thread of the cables.

Minidumper – Does not move even if the gear is engaged and the clutch is pulled
Minidumper

Please check the adjustment of the clutch cable. If it is not due to the adjustment, the V-belt must be tightened by moving the engine (slotted holes on the base plate).

How has a 400V log splitter put into use?
For all 400V machines

400V machines must always be connected with 3 phases and a ground.

With a 4-wire wiring the neutral conductor is not needed, for 5-wire wiring a neutral conductor must be connected (Please note this also for any extension cables which may be used)!

400V motors that only run on 2 phases get hot very quickly and thus trigger the overload protection or break down.

For the further steps of commissioning the log splitter, please refer to the operating instructions.

 

What to do if the log splitter is running but has no power? The machine switches off or overheats?
For all 400V machines

Please check the electrical connection and the supply cable of your machine (also the extension cable if it is used).

400V machines must always be connected with 3 phases and the ground.

With a 4-wire wiring the neutral conductor is omitted, with a 5-wire wiring also a neutral conductor must be connected!

400V motors that only run on 2 phases get hot very quickly and thus trigger the overload protection or break down.

Please check also with a possibly existing drive belt whether this is sufficiently tightened.

Please check the engine oil level.

The engine is equipped with an oil low protection, which does not release the ignition if the oil level is too low. The engine oil must be filled up until the oil can be seen at the filler opening by the thread.

Can I use the generator to power the household grid or run the heating system?
power generator

For these applications, it is essential to consult an electrician for inspection. If you are working with sensitive devices or controls, use an inverter..

The generator switches to overload protection and does not longer supply power
power generator

Before buying a generator, you should check the rated power of the consumers (nameplate watts or KW information) which you want to connect and plan reserves. For inductive loads (e.g.: pumps, saws, drills,...) a significantly increased power can be required for the start ( ca 3 x higher), which can activate the overload protection of the generator (especially if it is at the design power limit).

Is the starter battery included in the package of generators with an electric starter?
power generator

YES - The battery is included in all generators with an electric starter.

Is there an exhaust hose for the generators?
power generator

ATTENTION: Please do never use the power generator in closed rooms, this is an extreme danger to life because of the exhaust fumes. Even if you want to discharge the exhaust gases, you will not be able to completely prevent some of it from escaping. We do not carry connectors for exhaust gas discharge and clearly point out that the power generator has not be used in closed rooms.

Can a diesel generator be operated with fuel oil?
power generator

Operation with fuel oil is not recommended because fuel oil has a higher sulfur content than diesel. In addition, there are no minimum requirements regarding the cetane number for fuel oil (describes the ignitability of the fuel), which could lead to strong nailing and soot emission.
