5 Operations
There are a series of operational guidelines for the MAKSIWA LD.300 sander that must be followed.
These guidelines aim to increase the life of your equipment and oer safe and risk-free work for the
operator. This product is designed to perform operations on straight, curved, radial and chamfered
parts in wood, plastics, metals and ceramics. Used correctly, you will have high performance and
precision equipment for many years free of problems and defects.
ATTENTION! Accidental contact with the sandpaper during the operation can remove parts of the
ngers or cause major injuries. Protective Gloves and Guards reduce this risk and should always be
used when operating this machine.
1. Before making any adjustments or replacing parts of the equipment, turn o the machine and
remove the plug from the outlet.
2. Check that all screws and handles are properly tightened and secured before starting any
process. Often, due to some vibration, these parts tend to loosen on their own.

12
3. All moving parts (sandpaper, shafts and motor) must have enough space to move freely.
4. Wait for the sandpaper to reach its maximum speed before starting to operate (about 2 seconds).
5. The motor must rotate counterclockwise, as well as the sanding disc.
6. Do not force the workpiece excessively on any surface of the sandpaper.
7. Always support the workpiece when sanding.
8. Do not try to quickly push a corner of a workpiece against the sandpaper. This can cause a bump
that can result in serious personal injury.
9. The Stop or Quick Stop Lever is installed on the upper rear part of the tape le to break the disc
after the machine is turned o. Do not attempt to use this device while the machine is running.
10. When sanding small workpieces or with convex edges, disc sanding is the best option to achieve
good results.
11. Move the piece to the left side for the sandpaper to pull the material down.
12. Always use the table to support the workpiece. Do not operate this sandpaper freehand.
13. For accurate work, use the Angle Guide.
14. When sanding long pieces, do not apply pressure to the entire surface along the piece. Apply
pressure only to the area over the sandpaper, removing material. Consult the MAKSIWA catalog
for information on other equipment to support long parts.
15. The workpiece must be passed equally across its surface by sandpaper.
16. To make accurate 90º angles, make sure that the table and the sandpaper are perfectly square.
ATTENTION: This equipment is not designed to remove heavy burrs. Finishing ferrous metals can
generate sparks that can cause re. To prevent this possibility, remove the dust collector assembly,
remove all dust or wood sawdust that may have accumulated around and in the machine itself. In
addition, mixing dust from ferrous and non-ferrous materials can create a dangerous environment.
6 Maintenance
Periodic maintenance on your LD.300 MAKSIWA sander will guarantee optimum performance. Make
it a habit to inspect your sander every time you use it.
This section covers the most common service adjustments or procedures that may need to be made
during the life of your machine.
Check whether the following repair or replacement conditions are necessary:
• Loose or loose screws.
• Switch worn.
• Worn or damaged cables, plugs or sockets.

13
• Any other condition that could impair the safe operation of this equipment.
6.1 Table and Support Base
• Cleaning the LD.300 sander is relatively easy with a vacuum cleaner to remove excess wood
chips and sawdust, and dust with a dry cloth. If there is any resin, use a resin remover and a clean
cloth to remove it.
• Protect the unpainted cast iron surfaces on the table by wiping the table clean after each
use, which ensures moisture from wood dust does not remain in contact with untreated metal
surfaces.
• Make regular applications of anti-rust or a quality metal protector.
• Always remove dust accumulated on moving parts, such as axles and the motor. Lack of cleanliness
and excess of dirt can block some moving part, preventing the sandpaper from moving freely.
6.2 Lubrication
Since all bearings are shielded and permanently lubricated, just leave them in this way until they
need to be replaced. Do not lubricate them. For the other items on this machine, an occasional
application of electric machine oil is all that is needed. Before applying the lubricant, clean the
sawdust. Its objective is to achieve adequate lubrication. Too much lubrication will attract dirt and
sawdust. Various parts of your machine can lose their freedom of movement with excess dirt caused
by excessive lubrication.
6.3 Maintenance Schedule
Daily:
• Vacuum all the dust from above and around the machine.
• Clean the table and all unpainted cast iron with a metal protector.
Monthly:
• Check the sander for damage or wear.
• Clean the accumulation of dust inside and outside the engine.
6.4 Replacement of Garbage
Install the sandpaper as follows: Remove the support table from the front of the disc. Peel o the
adhesive lm from the back of the 12 ’’ sandpaper and carefully apply it to the disc.

14
Reposition the support table in front of the sandpaper.
Important: for the application to be ecient, the aluminum disc must be clean, free of any particles
of dirt and oil. When applied with dirt, the sandpaper can come o when in operation, which can
cause serious personal injury.
6.5 Grinding Quality
The smoothness of any surface depends on a number of variables. Factors such as the type of
material being sanded, type of sandpaper and pressure on the sandpaper contribute to the quality
of sanding.
Make sure that the material does not vibrate during the process.
6.6 Support for Long Pieces
ALWAYS SUPPORT LONG PARTS.
Support long pieces using any convenient shape such as easels or similar structures to prevent the
ends from falling.
CONSULT THE MAKSIWA CATALOG AND FIND PRODUCTS FOR THIS FUNCTION.
7 Technical Assistance
For your greater safety, maintenance and adjustments (including inspection and replacement)
contact technical assistance recommended by MAKSIWA, which will always use genuine spare parts
and accessories, reassembling your sander in the same way as the original.
