GREASE GUN SAFETY REQUIREMENTS

Tool or hose components may break under high pressure. Always check the tool for damage or wear before using it. Never use the tool with damaged or worn parts.

Use only approved hoses. Only use hoses identical to those factory-fitted to the tool or specified by the manufacturer.

If the hose is twisted, kinked or damaged, it can cause serious injury. Replace the hose at the first sign of wear, twist or damage.

Use only the grease recommended in the manual. Using other greases may cause injuries.

Stop the mechanisms for the time of grease application. Using the grease gun near moving parts can result in serious injury. The grease is discharged from the tool under high pressure. Never point the grease gun outlet towards you or towards other people or animals. Always use protective gloves and protective clothing with long sleeves and legs when handling the grease gun.

Risk of fire. The grease can be flammable. Do not expose grease to high temperatures or fire. Read the information supplied with the grease before using it.

TOOL OPERATION

Preparing for operation

Warning! Before beginning preparation activities, make sure that the tool is disconnected from the power supply. The battery must be removed from the tool's socket.

Caution! It is forbidden to use substances other than solid greases. In particular, it is forbidden to use agents bonding when exposed to air, such as silicones, sealing compounds or adhesives.

Caution! Before filling the tank with grease, thoroughly clean the tank and the grease gun from the remnants of the previous grease. Different greases can react with each other, causing health hazards and damage to the tool. If the residues of the previously used grease are inside the grease, after filling the tank with a new grease, the grease gun outlet should be aimed at a safe place and the trigger pressed until only the new grease starts to come out.

Unscrew the outlet valve (II).

Grasp the tool handle with one hand and the grease tank piston handle with the other. Pull the piston handle until it can be locked by sliding it in the cylinder cover opening (III).

Unscrew the tank cover and remove it together with the piston (IV). When unscrewing, be careful not to unlock the piston. Make sure that the piston seal faces the inside of the piston (V). Install the cover by fixing it to the tank, then unlock the piston and lower it as far as possible. A small amount of grease can escape through the outlet valve.

Caution! There may be a small amount of grease inside the cylinder, which is necessary for the factory test of the tool, as well as for the maintenance of metal parts during transport and storage.

Unscrew the grease tank, push the tank piston in completely. Place the tank in a container with grease so that the open end of the tank is about 5 cm below the grease level. Slowly pull out the tank piston, filling it with grease to the desired volume. Next, lock the piston. Remove grease from the outer surface of the tank, then carefully fix the tank to the grease gun. Release the piston lock and push it as far as possible to remove any remaining air from inside the tank. Close the outlet valve.

Caution! If the grease proves to be too thick to fill the tank as described above, the grease can be applied with an additional tool (e.g. a spatula) to the inside of the tank.

The grease gun has a hose bracket which facilitates transport and storage (VI). The hose tip should be protected with the cover which will reduce the risk of contamination of the hose tip.

Battery installation

Only the following 18V Li-Ion YATO batteries can be used to power the tool: YT-82842, YT-82843, YT-82844 and YT-82845, which can only be charged with YATO YT-82848 or YT-82849 chargers. It is forbidden to use other batteries with a different rated voltage and not matching the tool battery socket. It is forbidden to modify the socket or battery to make them match.

Slide the charged battery into the guides of the battery socket so that the battery latch holds it in place (VII). Check whether the battery does not slide out of the tool socket by itself.

Grease gun operation

After filling the tank with grease, remove the remnants of the old grease and the remaining air from inside the tank.

Unhook the hose from the handle and uncover its tip, which should be aimed at a safe spot, e.g. inside the tank.

The tool switch has a lock to prevent the tool from starting accidentally. The lock blocks the switch if it is set to the closed padlock symbol and unlocks the switch when it is set to the open padlock symbol.

EN

Unlock the switch, press and hold. After a while, the grease should start to flow out of the hose tip. If the grease comes out in a uniform flow, it means that the air has been pushed out of the tank.

Set the desired capacity by turning the regulator. The higher the number on the regulator, the higher the tool output.

Release the pressure on the power switch and check whether the grease has stopped coming out of the hose tip. Block the possibility of pressing the switch. Remove any excess grease from the hose tip and secure it with the cover if the grease gun is not in use.

If grease is applied, the hose tip should be placed on the grease nipple and held pressed against the grease nipple. Unlock the switch, push it and hold it down throughout the grease application process. When the application is finished, release the pressure on the switch and block the possibility of pressing it, and only then disconnect the hose tip from the grease nipple. Disconnecting the tip from the grease nipple while the switch is pressed will result in grease flowing out of the hose tip.

If the grease starts to escape from the safety valve, it means that the grease outlet through the hose has been clogged. In this case, stop applying the grease immediately and remove the cause of clogging. In this case, disassemble the tank and check that there are no impurities in the grease blocking its application.

If there is no grease coming out of the hose outlet after pressing the switch, it may mean that the grease tank has been emptied. If the tank is full and grease is still not coming out of the hose tip, clean the safety valve. To do this, loosen the screw located in the valve, remove the valve's components, clean them and reassemble. The order of the components' assembly is shown in figure (VIII).

Caution! Disconnect the battery from the tool socket before removing the safety valve.

Safety recommendations for battery loading

Attention! Before loading may start make sure the body of the charger, the cable and the plug are not broken or damaged. It is prohibited to use a damaged loading dock and charger! For the purpose of loading batteries only the charging dock and the charger provided may be used. Using another charger may be a cause of fire or damage the tool. Batteries may be charged only in a dry room, protected from unauthorised persons, particularly children. Do not use the charging dock and the charger without permanent supervision of an adult! If it is necessary to leave the room where loading is taking place, it is required to disconnect the charger from the mains, removing the charger from the mains socket. In case when smoke comes out of the charger, or a strange smell is emitted, etc., it is required to immediately remove the plug of the charger from the mains socket!

The drill and automatic return screwdriver is provided with an unloaded battery, so before work may commence, it is required to charge it following the procedure below, using the charger and charging dock provided. Li-ION batteries do not show the so called “memory effect”, so it is allowed to charge them at any moment. However, it is recommended to discharge them during normal work, and then load them to their full capacity. If due to the nature of the task it is not possible to do so each time, then it is required to do it at least from time to time. Under no circumstances is it allowed to discharge the batteries short-circuiting the electrodes, since this would cause irreversible damage! It is also prohibited to check the load of the batteries, short-circuiting the electrodes for sparking.

Storage of the battery

In order to prolong the life of the battery, it is required to provide adequate storage conditions. The batteries can go through approximately 500 „loading - discharging” cycles. The battery must be stored between 0 and 30°C, at the relative humidity of 50%. In order to store the battery for a prolonged period, it is required to charge it to approximately 70% of its capacity. In case of prolonged storage, it is required to recharge the battery once a year. Do not permit excessive discharging of the battery, since this would reduce its life and may cause irreversible damage.

During storage, the battery will be gradually unloading due to leakage conductance. The process of automatic unloading depends on the temperature of storage, since the higher the temperature, the fastest the process. In case of incorrect storage of batteries, there is a danger of electrolyte leakage. In case of leakage, it is required to protect the leakage with neutralizing agent. In case of contact of electrolyte with the eyes, it is required to rinse the eyes abundantly, and then immediately seek medical assistance. It is prohibited to use a tool with a damaged battery.

In case the battery is completely worn out, it is required to deposit it at a special point dedicated to disposal of such waste.

Transport of the batteries

Lithium-ion batteries are in accordance with legal regulations treated as dangerous waste. The user of the tool may transport the tool with the battery or only batteries by land. Then no additional conditions must be complied with. In transport is realised by third parties (for example dispatch through courier service), then it is required to proceed in accordance with regulations for transport of dangerous materials. Before shipment, contact an authorised person.

It is prohibited to transport damaged batteries. During transport the battery must be removed from the tool, and the exposed contacts protected, e.g. with insulating tape. Protect the batteries so that they do not move inside the package during transport. It is also required comply with the national regulations for transport of dangerous materials.
