This standard applies to planers

3 Terms and definitions

This clause of Part 1 is applicable except as follows:

Trang 9

Planers are tested under load observing the conditions shown in Table Z101

Table Z101 – Test conditions

Orientation Planing along a horizontal surface of a softwood workpiece

The workpiece shall have the dimensions of 400 mm x B x 90 mm where B is the maximum planing width of the tool less 15 mm

The workpiece shall be firmly secured to the test rig using resilient material, which shall be mounted so that it does not have any significant resonance in the frequency range that can influence the test result

Tool bit Blade as specified for planing softwood The cutting depth shall be set

to maximum capacity Feed force As necessary for smoothly working without overloading the machine

Equal forces are applied to both handles avoiding excessive gripping forces

Test cycle Planing the complete length of 400 mm at maximum depth of cut

The measurement starts when the blade enters the wood and finishes when the blade leaves the wood

NOTE Examples of softwood are pine and fir

6.2.7.2 Declaration of the vibration total value

Z102) Advice to wear a dust mask

Planer safety warnings

– Wait for the cutter to stop before setting the tool down An exposed rotating cutter

may engage the surface leading to possible loss of control and serious injury

NOTE The above warning applies only to planers without an automatic closing guard

– Hold the power tool by insulated gripping surfaces only, because the cutter may

contact its own cord Cutting a "live" wire may make exposed metal parts of the power

tool "live" and could give the operator an electric shock

– Use clamps or another practical way to secure and support the workpiece to a stable

platform Holding the work by your hand or against the body leaves it unstable and may

lead to loss of control

An overspeed test shall be made on a sample cutting head, equipped with blades for the largest cutting diameter and the largest cutting edge width, the test speed being 1,5 times the rated no-load speed If applicable, tension elements such as clamping screws shall be tightened in accordance with the instructions required by 8.12.2

After the test, the cutting head shall not be deformed or cracked, no screws shall be loosened and displacements of detachable parts shall be less than specified in the test procedure The test procedure is as follows:

1) Measure the cutting head dimensions

2) Bring the cutting head to the rated no-load speed, for 1 min

3) Stop and re-measure the cutting head; measured displacements of the detachable parts of the cutting head shall not be greater than 0,15 mm

4) Bring the cutting head to the test speed, for 1 min

5) Stop and re-measure the cutting head and compare the results with those obtained from step 3 The compared displacements shall not exceed 0,15 mm

19.105 The clamping screws or other tensile loaded blade fixing elements used to secure

the blades in the cutter block shall be made of steel with a hardness of at least 20 HRC and a tensile strength of at least 800 N/mm2

Clamping screws or bolts shall not project beyond the cutter block as shown in Figure 101

Compliance is checked by verification of the material specification and by inspection

19.106 It shall not be possible to touch rotating parts from the sides of the planer

Compliance is checked by the following test:

The planer is positioned with the shoes resting on a flat surface The accessibility of rotating parts is checked by means of the test probe shown in Figure 102

19.107 Planers with rabbeting facilities shall be provided with a guard that avoids

inadvertent contact at the sides with the blades

Compliance is checked by inspection and by applying the test probe of Figure 102 without any force with the planer in the same position as required in 19.106

19.108 It shall not be possible to touch the blades through the chip ejection opening

Compliance is checked by testing all apertures for chip ejection with the test probe of Figure 102 It shall not be possible to touch the blades in the cutting head at any angle of the probe

!19.103 The blades shall be secured in the cutter block in such a way that friction alone is not

relied upon to prevent the ejection of the blades

Compliance is checked by measurement and by inspection

19.104 Cutting heads shall be designed and made of such materials that they withstand the

forces and loads expected in normal use

Compliance is checked by the following test:

"

Trang 13

The guard provided shall return automatically to the closed position at the end of the planing operation The parallel guide and guard shall be so designed that for any cutting width the unused part of the cutting head is covered

Any contact between guards manufactured from steel and other hard materials and the blades

is to be avoided If either the guard or parallel guide is designed in such a way that elimination of contact with the cutting head cannot be ensured, they shall be manufactured from soft material (e.g aluminium, plastic, wood)

Compliance is checked by inspection

NOTE Examples of parallel guide and guard are given in Figure 103

19.110 Planers shall stop within 10 s of switching off, unless the tool is fitted with an

automatic closing guard

Compliance is checked by inspection and by measurement

!

"

19.109 If a parallel guide is provided, its guiding and top surface shall have no openings or

projections Openings having a maximum dimension not exceeding 10 mm are disregarded

Planers may be provided with an integrated non-detachable and non-lockable guard which automatically moves to the closed position, where it covers the whole width of the cutting head, when the planer is not in use

19.111 If a lift-off device is provided, it shall be designed so that

– it is automatically activated, when the planer is lifted up from a horizontal surface, and – the blade(s) do not make contact, when the planer is set at maximum depth of cut and placed on a horizontal surface

Compliance is checked by inspection
